l How to configure and Manage FortiAP-S from FortiCloud

FortiCloud-managed FortiAP WiFi

In this example, you use FortiCloud to configure a single FortiAP-221C, creating a working WiFi network without a FortiGate.

FortiCloud remote management is supported on FortiAP models 221C and 320C.

For this configuration, the FortiAP-221C unit is running version 5.2 firmware. You will create a simple network that uses WPA-Personal authentication.

You can register for a free FortiCloud account at www.forticloud.com.

To create the WiFi network without a FortiGate unit, you must:

l Add your FortiAP to FortiCloud l Configure the SSID l Configure the AP platform profile l Deploy the AP with the profile

Adding your FortiAP to FortiCloud

You need to add the FortiAP unit to your FortiCloud account. This is done through a unique key that can be found under the FortiAP unit.

To add a FortiAP to FortiCloud

  1. Connect the FortiAP Ethernet interface to a network that provides access to the Internet.
  2. Open a web browser and navigate to the FortiCloud main page and select + AP Network.
  3. Enter an AP Network Name and AP Password. This password is used to locally log in to the AP as the administrator. It will be set to all APs in this AP network.
  4. Set the correct Time Zone and select Submit.

Configuring the SSID

You must establish the SSID (network interface) for the WiFi network.

To configure the SSID

  1. Select the FortiAP you just created from the home page. You will then be prompted to add an SSID for the AP Network.

In the interface, this is under Configure > SSIDs.

  1. In Access Control, enter the name of your SSID, set Authentication to WPA2-Personal, enter the Preshared Key, and select Next.
  2. In Security, enable security features as required (select from AntiVirus, Intrusion Prevention, Block Botnet, Web Access, and Application Control) and select Next.
  3. In Availability, make sure to leave 5 GHz enabled, configure a schedule as required, and select Next.
  4. Review your SSID in Preview, then select Apply.

Configuring the AP platform profile

The radio portion of the FortiAP configuration is contained in the FortiAP platform profile. By default, there is a profile for each platform (FortiAP model). The SSID needs to be specified in the profile.

To configure the AP profile

  1. Go to Configure > AP Profile and edit the AP Profile for your FortiAP model (mouse-over the AP Profile to reveal the Edit button).
  2. Enable the SSID configured earlier for both Radio 1 and Radio 2, for 5GHz coverage.

Deploying the AP with the platform profile

With the SSID and platform profile configured, you must deploy the AP by entering the FortiCloud key for the FortiAP.

To deploy the AP

  1. Go to Configure > Deploy APs. Here you will be prompted to enter the FortiCloud key, which can be found on the same label as the FortiAP unit’s serial number, and select Submit.

If you have a FortiAP model that does not include a FortiCloud key, you can still add the device to the network. To learn how, see the FortiCloud-managed FortiAP WiFi without a key configuration.

end

Connecting the FortiAP units

You need to connect each FortiAP unit to the FortiGate unit, wait for it to be recognized, and then assign it to the AP Profile. But first, you must configure the interface to which the FortiAP units connect and the DHCP server that assigns their IP addresses.

In this example, the FortiAP units connect to port 3 and are controlled through IP addresses on the 192.168.8.0/24 network.

To configure the interface for the AP unit – web-based manager

  1. Go to Network > Interfaces and edit the port3 interface.
  2. Set the Addressing mode to Dedicated to Extension Device and set the IP/Network Mask to 168.8.1/255.255.255.0.
  3. Select OK.

Basic wireless network

This procedure automatically configures a DHCP server for the AP units.

To configure the interface for the AP unit – CLI

config system interface edit port3 set mode static

set ip 192.168.8.1 255.255.255.0

end

To configure the DHCP server for AP units – CLI

config system dhcp server edit 0 set interface port3 config exclude-range edit 1 set end-ip 192.168.8.1 set start-ip 192.168.8.1

end

config ip-range edit 1 set end-ip 192.168.8.254 set start-ip 192.168.8.2

end set netmask 255.255.255.0 set vci-match enable set vci-string “FortiAP”

wtp-id: FAP22B3U10600118

  1. Edit the discovered FortiAP unit like this:

edit FAP22B3U10600118 set admin enable

end

  1. Repeat Steps 2 through 4 for each FortiAP unit.

A more complex example

This example creates multiple networks and uses custom AP profiles.

Scenario

In this example, Example Co. provides two wireless networks, one for its employees and the other for customers or other guests of its business. Guest users have access only to the Internet, not to the company’s private network. The equipment for these WiFi networks consists of FortiAP-220B units controlled by a FortiGate unit.

The employee network operates in 802.11n mode on both the 2.4GHz and 5GHz bands. Client IP addresses are in the 10.10.120.0/24 subnet, with 10.10.120.1 the IP address of the WAP. The guest network also operates in 802.11n mode, but only on the 2.4GHz band. Client IP addresses are on the 10.10.115.0/24 subnet, with 10.10.115.1 the IP address of the WAP.

On FortiAP-220B units, the 802.11n mode also supports 802.11g and 802.11b clients on the 2.4GHz band and 802.11a clients on the 5GHz band.

The guest network WAP broadcasts its SSID, the employee network WAP does not.

The employees network uses WPA-Enterprise authentication through a FortiGate user group. The guest network features a captive portal. When a guest first tries to connect to the Internet, a login page requests logon credentials. Guests use numbered guest accounts authenticated by RADIUS. The captive portal for the guests includes a disclaimer page.

In this example, the FortiAP units connect to port 3 and are assigned addresses on the 192.168.8.0/24 subnet.

Configuration

To configure these wireless networks, you must:

l Configure authentication for wireless users l Configure the SSIDs (network interfaces) l Configure the AP profile l Configure the WiFi LAN interface and a DHCP server l Configure firewall policies

Configuring authentication for employee wireless users

Employees have user accounts on the FortiGate unit. This example shows creation of one user account, but you can create multiple accounts and add them as members to the user group.

To configure a WiFi user – web-based manager

  1. Go to User & Device > User Definition and select Create New.
  2. Select Local User and then click Next.
  3. Enter a User Name and Password and then click Next.
  4. Click Next.
  5. Make sure that Enable is selected and then click Create.

To configure the user group for employee access – web-based manager

  1. Go to User & Device > User Groups and select Create New.
  2. Enter the following information and then select OK:
Name employee-group
Type Firewall
Members Add users.

To configure a WiFi user and the user group for employee access – CLI

config user user edit “user01” set type password set passwd “asdf12ghjk”

end

config user group edit “employee-group” set member “user01”

end

The user authentication setup will be complete when you select the employee-group in the SSID configuration.

Configuring authentication for guest wireless users

Guests are assigned temporary user accounts created on a RADIUS server. The RADIUS server stores each user’s group name in the Fortinet-Group-Name attribute. Wireless users are in the group named “wireless”.

The FortiGate unit must be configured to access the RADIUS server.

To configure the FortiGate unit to access the guest RADIUS server – web-based manager

  1. Go to User & Device > RADIUS Servers and select Create New.
  2. Enter the following information and select OK:
Name guestRADIUS
Primary Server IP/Name 10.11.102.100
Primary Server Secret grikfwpfdfg
Secondary Server IP/Name Optional
Secondary Server Secret         Optional
Authentication Scheme          Use default, unless server requires otherwise.
Leave other settings at their default values.

To configure the FortiGate unit to access the guest RADIUS server – CLI

config user radius edit guestRADIUS set auth-type auto set server 10.11.102.100 set secret grikfwpfdfg

end

To configure the user group for guest access – web-based manager

  1. Go to User & Device > User Groups and select Create New.
  2. Enter the following information and then select OK:
Name guest-group
Type Firewall
Members Leave empty.
  1. Select Create new.
  2. Enter:

Wireless network monitoring

You can monitor both your wireless clients and other wireless networks that are available in your coverage area.

Monitoring wireless clients

Monitoring rogue APs

Suppressing rogue APs

Monitoring wireless network health

Monitoring wireless clients

To view connected clients on a FortiWiFi unit

  1. Go to Monitor > Client Monitor.

The following information is displayed:

SSID The SSID that the client connected to.
FortiAP The serial number of the FortiAP unit to which the client connected.
User User name
IP The IP address assigned to the wireless client.
Device  
Auth The type of authentication used.
Channel WiFi radio channel in use.
Bandwidth Tx/Rx Client received and transmitted bandwidth, in Kbps.
Signal Strength / Noise The signal-to-noise ratio in deciBels calculated from signal strength and noise level.
Signal Strength  
Association Time How long the client has been connected to this access point.

Results can be filtered. Select the filter icon on the column you want to filter. Enter the values to include or select NOT if you want to exclude the specified values.

Monitoring rogue APs

The access point radio equipment can scan for other available access points, either as a dedicated monitor or in idle periods during AP operation.

Discovered access points are listed in Monitor > Rogue AP Monitor. You can then mark them as either Accepted or Rogue access points. This designation helps you to track access points. It does not affect anyone’s ability to use these access points.

It is also possible to suppress rogue APs. See Monitoring rogue APs on page 115.

On-wire rogue AP detection technique

Other APs that are available in the same area as your own APs are not necessarily rogues. A neighboring AP that has no connection to your network might cause interference, but it is not a security threat. A rogue AP is an unauthorized AP connected to your wired network. This can enable unauthorized access. When rogue AP detection is enabled, the On-wire column in the Rogue AP Monitor list shows a green up-arrow on detected rogues.

Rogue AP monitoring of WiFi client traffic builds a table of WiFi clients and the Access Points that they are communicating through. The FortiGate unit also builds a table of MAC addresses that it sees on the LAN. The FortiGate unit’s on-wire correlation engine constantly compares the MAC addresses seen on the LAN to the MAC addresses seen on the WiFi network.

There are two methods of Rogue AP on-wire detection operating simultaneously: Exact MAC address match and MAC adjacency.

Exact MAC address match

If the same MAC address is seen on the LAN and on the WiFi network, this means that the wireless client is connected to the LAN. If the AP that the client is using is not authorized in the FortiGate unit configuration, that AP is deemed an ‘on-wire’ rogue. This scheme works for non-NAT rogue APs.

MAC adjacency

If an access point is also a router, it applies NAT to WiFi packets. This can make rogue detection more difficult.

However, an AP’s WiFi interface MAC address is usually in the same range as its wired MAC address. So, the MAC adjacency rogue detection method matches LAN and WiFi network MAC addresses that are within a defined numerical distance of each other. By default, the MAC adjacency value is 7. If the AP for these matching MAC addresses is not authorized in the FortiGate unit configuration, that AP is deemed an ‘on-wire’ rogue.

Limitations

On-wire rogue detection has some limitations. There must be at least one WiFi client connected to the suspect AP and continuously sending traffic. If the suspect AP is a router, its WiFi MAC address must be very similar to its Ethernet port MAC address.

Logging

Information about detected rogue APs is logged and uploaded to your FortiAnalyzer unit, if you have one. By default, rogue APs generate an alert level log, unknown APs generate a warning level log. This log information can help you with PCI-DSS compliance requirements.

Rogue AP scanning as a background activity

Each WiFi radio can perform monitoring of radio channels in its operating band while acting as an AP. It does this by briefly switching from AP to monitoring mode. By default, a scan period starts every 300 seconds. Each second rogue APs

a different channel is monitored for 20ms until all channels have been checked.

During heavy AP traffic, it is possible for Spectrum Analysis background scanning to cause lost packets when the radio switches to monitoring. To reduce the probability of lost packets, you can set the CLI ap-bgscan-idle field to delay the switch to monitoring until the AP has been idle for a specified period. This means that heavy AP traffic may slow background scanning.

The following CLI example configures default background rogue scanning operation except that it sets apbgscan-idle to require 100ms of AP inactivity before scanning the next channel.

config wireless-controller wtp-profile edit ourprofile config radio-1 set wids-profile ourwidsprofile set spectrum-analysis enable

end

end

config wireless-controller wids-profile edit ourwidsprofile set ap-scan enable set rogue-scan enable set ap-bgscan-period 300 set ap-bgscan-intv 1 set ap-bgscan-duration 20 set ap-bgscan-idle 100

end

Configuring rogue scanning

All APs using the same FortiAP Profile share the same rogue scanning settings, unless override is configured.

To enable rogue AP scanning with on-wire detection – web-based manager

  1. Go to WiFi & Switch Controller > WIDS Profiles.

On some models, the menu is WiFi & Switch Controller.

  1. Select an existing WIDS Profile and edit it, or select Create New.
  2. Make sure that Enable Rogue AP Detection is selected.
  3. Select Enable On-Wire Rogue AP Detection.
  4. Optionally, enable Auto Suppress Rogue APs in Foreground Scan.
  5. Select OK.

To enable the rogue AP scanning feature in a custom AP profile – CLI

config wireless-controller wids-profile edit FAP220B-default set ap-scan enable set rogue-scan enable

end

Exempting an AP from rogue scanning

By default, if Rogue AP Detection is enabled, it is enabled on all managed FortiAP units. Optionally, you can exempt an AP from scanning. You should be careful about doing this if your organization must perform scanning to meet PCI-DSS requirements.

To exempt an AP from rogue scanning

  1. Go to WiFi & Switch Controller > WIDS Profiles.
  2. Create a new WIDS profile and disable Rogue AP detection.
  3. Go to WiFi & Switch Controller > FortiAP Profiles and edit the profile you wish to exempt from rogue scanning.
  4. Assign the WIDS profile created in step 2.

MAC adjacency

You can adjust the maximum WiFi to Ethernet MAC difference used when determining whether an suspect AP is a rogue.

To adjust MAC adjacency

For example, to change the adjacency to 8, enter

config wireless-controller global set rogue-scan-mac-adjacency 8 end

Using the Rogue AP Monitor

Go to Monitor > Rogue AP Monitor to view the list of other wireless access points that are receivable at your location.

Information Columns

Actual columns displayed depends on Column Settings.
Rogue AP — Use this status for unauthorized APs that On-wire status indicates are attached to your wired networks.

Accepted AP — Use this status for APs that are an authorized part of your network or

Stateare neighboring APs that are not a security threat. To see accepted APs in the list, select Show Accepted.

To change the Online Status of an AP, right-click it and select Mark Accepted or Mark Rogue.

Suppressing rogue APs

In addition to monitoring rogue APs, you can actively prevent your users from connecting to them. When suppression is activated against an AP, the FortiGate WiFi controller sends deauthentication messages to the rogue AP’s clients, posing as the rogue AP, and also sends deauthentication messages to the rogue AP, posing as its clients. This is done using the monitoring radio.

To enable rogue AP suppression, you must enable monitoring of rogue APs with the on-wire detection technique. See “Monitoring rogue APs”. The monitoring radio must be in the Dedicated Monitor mode.

To activate AP suppression against a rogue AP

  1. Go to Monitor > Rogue AP Monitor.
  2. When you see an AP listed that is a rogue detected “on-wire”, select it and then select Mark > Mark Rogue.
  3. To suppress an AP that is marked as a rogue, select it and then select Suppress AP.

To deactivate AP suppression

  1. Go to Monitor > Rogue AP Monitor.
  2. Select the suppressed rogue AP and then select Suppress AP > Unsuppress AP.

Monitoring wireless network health

To view the wireless health dashboard, go to Monitor > WiFi Health Monitor.

The wireless health dashboard provides a comprehensive view of the health of your network’s wireless infrastructure. The dashboard includes widgets to display: l AP Status

Active, Down or missing, up for over 24 hours, rebooted in past 24 hours l Client Count Over Time

Viewable for past hour, day, or 30 days l Top Client Count Per-AP

Separate widgets for 2.4GHz and 5GHz bands health

l Top Wireless Interference

Separate widgets for 2.4GHz and 5GHz bands, requires spectrum analysis to be enabled on the radios l Login Failures Information l WiFi Channel Utilization

Three views allowing users to view top 10-20 Most and Least utilized channels for each AP radio and a third histogram view showing counts for utilization

The list of active clients also shows MAC address entries (similar to the WiFi Client Monitor page), making client information easy to view when opening the Active Client widget.

FortiAP-S UTM support

DHCP snooping and option 82 (circuit -id) options for wireless access points

Wireless IDS

The FortiGate Wireless Intrusion Detection System (WIDS) monitors wireless traffic for a wide range of security threats by detecting and reporting on possible intrusion attempts. When an attack is detected the FortiGate unit records a log message.

You can create a WIDS profile to enable these types of intrusion detection:

  • Asleap Attack—ASLEAP is a tool used to perform attacks against LEAP authentication.
  • Association Frame Flooding—A Denial of Service attack using a large number of association requests. The default detection threshold is 30 requests in 10 seconds.
  • Authentication Frame Flooding—A Denial of Service attack using a large number of association requests. The default detection threshold is 30 requests in 10 seconds.
  • Broadcasting De-authentication—This is a type of Denial of Service attack. A flood of spoofed de-authentication frames forces wireless clients to de-athenticate, then re-authenticate with their AP.
  • EAPOL Packet Flooding—Extensible Authentication Protocol over LAN (EAPOL) packets are used in WPA and WPA2 authentication. Flooding the AP with these packets can be a denial of service attack. Several types of EAPOL packets are detected: EAPOL-FAIL, EAPOL-LOGOFF, EAPOL-START, EAPOL-SUCC.
  • Invalid MAC OUI—Some attackers use randomly-generated MAC addresses. The first three bytes of the MAC address are the Organizationally Unique Identifier (OUI), administered by IEEE. Invalid OUIs are logged.
  • Long Duration Attack—To share radio bandwidth, WiFi devices reserve channels for brief periods of time. Excessively long reservation periods can be used as a denial of service attack. You can set a threshold between 1000 and 32 767 microseconds. The default is 8200. l Null SSID Probe Response—When a wireless client sends out a probe request, the attacker sends a response with a null SSID. This causes many wireless cards and devices to stop responding.
  • Spoofed De-authentication—Spoofed de-authentication frames are a denial of service attack. They cause all clients to disconnect from the AP.
  • Weak WEP IV Detection—A primary means of cracking WEP keys is by capturing 802.11 frames over an extended period of time and searching for patterns of WEP initialization vectors (IVs) that are known to be weak. WIDS detects known weak WEP IVs in on-air traffic.
  • Wireless Bridge—WiFi frames with both the fromDS and ToDS fields set indicate a wireless bridge. This will also detect a wireless bridge that you intentionally configured in your network.

You can enable wireless IDS by selecting a WIDS Profile in your FortiAP profile.

To create a WIDS Profile

  1. Go to WiFi & Switch Controller > WIDS Profiles.
  2. Select a profile to edit or select Create New.
  3. Select the types of intrusion to protect against. By default, all types are selected.
  4. Select Apply.

You can also configure a WIDS profile in the CLI using the config wireless-controller widsprofile command.

Rogue AP detection

The WIDS profile includes settings for detection of unauthorized (rogue) access points in your wireless network. For more information, see Wireless network monitoring on page 115.

WIDS client deauthentication rate for DoS attacks

As part of mitigating a Denial of Service (DoS) attack, the FortiGate sends deauthentication packets to unknown clients. In an aggressive attack, this deauthentication activity can prevent the processing of packets from valid clients. A WIDS Profile option in the CLI limits the deauthentication rate.

config wireless-controller wids-profile edit default set deauth-unknown-src-thresh <1-65535>

end

The value set is a measure of the number of deathorizations per second. 0 means no limit. The default is 10.

WiFi data channel encryption

Optionally, you can apply DTLS encryption to the data channel between the wireless controller and FortiAP units. This enhances security.

There are data channel encryption settings on both the FortiGate unit and the FortiAP units. At both ends, you can enable Clear Text, DTLS encryption, or both. The settings must agree or the FortiAP unit will not be able to join the WiFi network. By default, both Clear Text and DTLS-encrypted communication are enabled on the FortiAP unit, allowing the FortiGate setting to determine whether data channel encryption is used. If the FortiGate unit also enables both Clear Text and DTLS, Clear Text is used.

Data channel encryption settings are located in the FortiAP profile. By default, only Clear Text is supported.

Configuring encryption on the FortiGate unit

You can use the CLI to configure data channel encryption.

Enabling encryption

In the CLI, the wireless wtp-profile command contains a new field, dtls-policy, with options clear-text and dtls-enabled. To enable encryption in profile1 for example, enter:

config wireless-controller wtp-profile edit profile1 set dtls-policy dtls-enabled

end

Configuring encryption on the FortiAP unit

The FortiAP unit has its own settings for data channel encryption.

Enabling CAPWAP encryption – FortiAP web-based manager

  1. On the System Information page, in WTP Configuration > AC Data Channel Security, select one of:

l Clear Text l DTLS Enabled l Clear Text or DTLS Enabled (default)

  1. Select Apply.

Enabling encryption – FortiAP CLI

You can set the data channel encryption using the AP_DATA_CHAN_SEC variable: ‘clear’, or ‘ipsec’, or ‘dtls’.

For example, to set security to DTLS and then save the setting, enter:

cfg -a AP_DATA_CHAN_SEC=dtls cfg -c

Protected Management Frames and Opportunisitc Key Caching support

Protected Management Frames (PMF) protect some types of management frames like deauthorization, disassociation and action frames. This feature, now mandatory on WiFi certified 802.1ac devices, prevents attackers from sending plain deauthorization/disassociation frames to disrupt or tear down a connection/association. PMF is a Wi-Fi Alliance specification based on IEEE 802.11w.

To facilitate faster roaming client roaming, you can enable Opportunistic Key Caching (OKC) on your WiFi network. When a client associates with an AP, its PMK identifier is sent to all other APs on the network. This eliminates the need for an already-authenticated client to repeat the full EAP exchange process when it roams to another AP on the same network.

Use of PMF and OKC on an SSID is configurable only in the CLI:

config wireless-controller vap edit <vap_name> set pmf {disable | enable | optional} set pmf-assoc-comeback-timeout <integer> set pmf-sa-query-retry-timeout <integer>

set okc {disable | enable}

next end

Protected Management Frames and Opportunisitc Key Caching support

When pmf is set to optional, it is considered enabled, but will allow clients that do not use PMF. When pmf is set to enable, PMF is required by all clients.

Bluetooth Low Energy (BLE) Scan

The FortiGate can configure FortiAP Bluetooth Low Energy (BLE) scan, incorporating Google’s BLE beacon profile known as Eddystone, used to identify groups of devices and individual devices.

Use the following syntax to configure BLE profiles, configure BLE report intervals, and assign BLE profiles to WTP profiles.

CLI syntax – Configure BLE profiles

config wireless-controller ble-profile edit <name> set comment <comment>

set advertising {ibeacon | eddystone-uid | eddystone-url} set ibeacon-uuid <uuid> set major-id <0 – 65535> – (default = 1000) set minor-id <0 – 65535> – (default = 1000) set eddystone-namespace <10-byte namespace> set eddystone-instance <device id> set eddystone-url <url> set txpower <0 – 12> – (default = 0) set beacon-interval <40 – 3500> – (default = 100) set ble-scanning {enable | disable} – (default = disable)

next

end

Note that txpower determines the transmit power level on a scale of 0-12:

0: -21 dBm 1: -18 dBm 2: -15 dBm 3: -12 dBm 4: -9 dBm
5: -6 dBm 6: -3 dBm 7: 0 dBm 8: 1 dBm 9: 2 dBm
10: 3 dBm 11: 4 dBm 12: 5 dBm    

CLI syntax – Configure BLE report intervals

config wireless-controller timers set ble-scan-report-intv – (default = 30 sec)

end

CLI syntax – Assign BLE profiles to WTP profiles

config wireless-controller wtp-profile edit <name> set ble-profile <name> next

end

Preventing local bridge traffic from reaching the LAN

The following command can be enabled so that when a client connects to a VAP, and its traffic is not tunneled to the controller, the admin can control whether the client can access the local network.

Note that this entry is only available when local-standalone-nat is set to enable.

Syntax:

config wireless-controller vap edit <name> set local-lan {allow | deny}

next

end

FortiAP-S UTM support

When a FortiAP-S is managed by a FortiGate in Bridge mode, support is provided for the following UTM functions: AntiVirus, IPS, Botnet, Web Filtering, and Application Control.

config wireless-controller utm-profile edit <name> set comment “Default configuration for offloading WiFi traffic.” set ips-sensor “wifi-default” set application-list “wifi-default” set antivirus-profile “wifi-default” set webfilter-profile “wifi-default”

set firewall-profile-protocol-options “wifi-default” set firewall-ssl-ssh-profile “wifi-default”

next

end

config wireless-controller vap edit <name> set utm-profile

end

end

DHCP snooping and option 82 (circuit -id) options for wireless access points

New commands are available to enable or disable (by default) DHCP 82 option insertion for wireless access points. DHCP snooping is used to prevent rogue DHCP servers from offering IP addresses to DHCP clients.

Syntax

config wireless-controll vap edit wifi set dhcp-option82-insertion {enable | disable}

set dhcp-option82-circuit-id-insertion {style-1 | style-2 | disable}

Access point deployment

Leave a reply

Access point deployment

Overview

FortiAP units discover WiFi controllers. The administrator of the WiFi controller authorizes the FortiAP units that the controller will manage.

In most cases, FortiAP units can find WiFi controllers through the wired Ethernet without any special configuration. Review the following section, Access point deployment on page 55, to make sure that your method of connecting the FortiAP unit to the WiFi controller is valid. Then, you are ready to follow the procedures in Access point deployment on page 55.

If your FortiAP units are unable to find the WiFi controller, refer to Access point deployment on page 55 for detailed information about the FortiAP unit’s controller discovery methods and how you can configure them.

Network topology for managed APs

The FortiAP unit can be connected to the FortiGate unit in any of the following ways:

Direct connection: The FortiAP unit is directly connected to the FortiGate unit with no switches between them.

This configuration is common for locations where the number of FortiAP’s matches up with the number of

‘internal’ ports available on the FortiGate. In this configuration the FortiAP unit requests an IP address from the FortiGate unit, enters discovery mode and should quickly find the FortiGate WiFi controller. This is also known as a wirecloset deployment. See “Wirecloset and Gateway deployments” below.

 

Wirecloset deployment

Switched Connection: The FortiAP unit is connected to the FortiGate WiFi controller by an Ethernet switch operating in L2 switching mode or L3 routing mode. There must be a routable path between the FortiAP unit and the FortiGate unit and ports 5246 and 5247 must be open. This is also known as a gateway deployment. See Gateway Deployment below.

Gateway Deployment

Network topology for managed

Connection over WAN: The FortiGate WiFi controller is off-premises and connected by a VPN tunnel to a local FortiGate. In this method of connectivity its best to configure each FortiAP with the static IP address of the WiFi controller. Each FortiAP can be configured with three WiFi controller IP addresses for redundant failover. This is also known as a datacenter remote management deployment. See Remote deployment below.

FortiAP CLI

FortiAP web-based manager

FortiAP web-based manager

You can access the FortiAP unit’s built-in web-based manager. This is useful to adjust settings that are not available through the FortiGate unit’s WiFi Controller. Logging into the FortiAP web-based manager is similar to logging into the FortiGate web-based manager.

System Information

Status

The Status section provides information about the FortiAP unit.

You can:

  • Select Change to change the Host Name. l Select Update in Firmware Version to upload a new FortiAP firmware file from your computer.
  • Select Change Password to change the administrator password. l Select Backup to save the current FortiAP configuration as a file on your computer. l Select Restore to load a configuration into your FortiAP unit from a file on your computer.

Network Configuration

Select DHCP or select Static and specify the IP address, netmask, and gateway IP address. Administrative Access settings affect access after the FortiAP has been authorized. By default, HTTP access needed to access the FortiAP web-based manager is enabled, but Telnet access is not enabled.

Connectivity

These settings determine how the FortiAP unit connects to the FortiGate WiFi controller.

FortiAP web-based manager

Uplink Ethernet – wired connection to the FortiGate unit (default)

Mesh – WiFi mesh connection

Ethernet with mesh backup support
Mesh AP SSID Enter the SSID of the mesh root. Default: fortinet.mesh.root
Mesh AP Password Enter password for the mesh SSID.
Ethernet Bridge Bridge the mesh SSID to the FortiAP Ethernet port.

This is available only whe Uplink is Mesh.

WTP Configuration

AC Discovery Type settings affect how the FortiAP unit discovers a FortiGate WiFi controller. By default, this is set to Auto which causes the FortiAP unit to cycle through all of the discovery methods until successful. For more information see Controller discovery methods.

AC Discovery Type Static, DHCP, DNS, Broadcast, Multicast, Auto
AC Control Port Default port is 5246.
AC IP Address 1

AC IP Address 2

AC IP Address 3

 You enter up to three WiFi controller IP addresses for static discovery. Routing must be properly configured in both directions.
AC Host Name 1

AC Host Name 2

AC Host Name 3

 As an alternetive to AC IP addresses, you can enter their fully qualified domain names (FQDNs).
AC Discovery

Multicast

Address

 224.0.1.140
AC Discovery

DHCP Option

Code

 When using DHCP discovery, you can configure the DHCP server to provide the controller address. By default the FortiAP unit expects this in option 138.

AC Data Channel Security by default accepts either DTLS-encrypted or clear text data communication with the WiFi controller. You can change this setting to require encryption or to use clear text only.

Wireless Information

The Wireless Information page provides current information about the operation of the radios and the type Uplink in use.
