Using a FortiWiFi unit as a client

A FortiWiFi unit by default operates as a wireless access point. But a FortiWiFi unit can also operate as a wireless client, connecting the FortiGate unit to another wireless network.

Use of client mode Configuring client mode

Use of client mode

In client mode, the FortiWiFi unit connects to a remote WiFi access point to access other networks or the Internet. This is most useful when the FortiWiFi unit is in a location that does not have a wired infrastructure.

For example, in a warehouse where shipping and receiving are on opposite sides of the building, running cables might not be an option due to the warehouse environment. The FortiWiFi unit can support wired users using its Ethernet ports and can connect to another access point wirelessly as a client. This connects the wired users to the network using the 802.11 WiFi standard as a backbone.

Note that in client mode the FortiWiFi unit cannot operate as an AP. WiFi clients cannot see or connect to the FortiWifi unit in Client mode.

Configuring client mode                                                                                          Using a FortiWiFi unit as a client

Configuring client mode

To set up the FortiAP unit as a WiFi client, you must use the CLI. Before you do this, be sure to remove any AP WiFi configurations such as SSIDs, DHCP servers, policies, and so on.

To configure wireless client mode

1. Change the WiFi mode to client.

In the CLI, enter the following commands:

config system global set wireless-mode client

end

Respond “y” when asked if you want to continue. The FortiWiFi unit will reboot.

2. Configure the WiFi interface settings.

For example, to configure the client for WPA-Personal authentication on the our_wifi SSID with passphrase justforus, enter the following in the CLI:

config system interface edit wifi set mode dhcp config wifi-networks edit 0 set wifi-ssid our_wifi set wifi-security wpa-personal set wifi-passphrase “justforus”

end

end

The WiFi interface client_wifi will receive an IP address using DHCP.

3. Configure a wifi to port1 policy.

You can use either CLI or web-based manager to do this. The important settings are:

Incoming Interface (srcintf)	wifi
Source Address (srcaddr)	all
Outgoing Interface (dstintf)	port1
Destination Address (dstaddr)	all
Schedule	always
Service	ALL
Action	ACCEPT
Enable NAT	Selected

end

5. 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:

• 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
• Configure firewall policies

Configuring authentication for employee wireless users

You need to connect each FortiAP-220A 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/Netmask to

192.168.8.1/255.255.255.0.

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

3. Select OK.

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 ip-range

edit 1 set end-ip 192.168.8.9 set start-ip 192.168.8.2

end

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

end

To connect a FortiAP-220A unit – web-based manager

1. Go to WiFi & Switch Controller > Managed FortiAPs.
2. Connect the FortiAP unit to port 3.
3. Periodically select Refresh while waiting for the FortiAP unit to be listed.

Recognition of the FortiAP unit can take up to two minutes.

If there is persistent difficulty recognizing FortiAP units, try disabling VCI-Match in the DHCP server settings.

4. When the FortiAP unit is listed, select the entry to edit it. The Edit Managed Access Point window opens.
5. In State, select
6. In the AP Profile, select [Change] and then select the example_AP
7. Select OK.
8. Repeat Steps 2 through 8 for each FortiAP unit.

To connect a FortiAP-220A unit – CLI

1. Connect the FortiAP unit to port 3.
2. Enter:

config wireless-controller wtp

3. Wait 30 seconds, then enter get.

Retry the get command every 15 seconds or so until the unit is listed, like this:

== [ FAP22A3U10600118 ] wtp-id: FAP22A3U10600118

4. Edit the discovered FortiAP unit like this:

edit FAP22A3U10600118 set admin enable set wtp-profile example_AP

end

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

Checking that client received IP address and DNS server information

Windows XP

1. Double-click the network icon in the taskbar to display the Wireless Network Connection Status

Check that the correct network is listed in the Connection section.

2. Select the Support

Check that the Address Type is Assigned by DHCP. Check that the IP Address, Subnet Mask, and Default Gateway values are valid.

3. Select Details to view the DNS server addresses.

The listed address should be the DNS serves that were assigned to the WAP. Usually a wireless network that provides access to the private LAN is assigned the same DNS servers as the wired private LAN. A wireless network that provides guest or customer users access to the Internet is usually assigned public DNS servers.

4. If any of the addresses are missing, select Repair.

If the repair procedure doesn’t correct the problem, check your network settings.

Troubleshooting

Mac OS

1. From the Apple menu, open System Preferences > Network.
2. Select AirPort and then select Configure.
3. On the Network page, select the TCP/IP
4. If there is no IP address or the IP address starts with 169, select Renew DHCP Lease.
5. To check DNS server addresses, open a terminal window and enter the following command:

cat /etc/resolv.conf

Check the listed nameserver addresses. A network for employees should us the wired private LAN DNS server. A network for guests should specify a public DNS server.

Linux

This example is based on the Ubuntu 10.04 Linux wireless client.

Troubleshooting

1. Right-click the Network Manager icon and select Connection Information.
2. Check the IP address, and DNS settings. If they are incorrect, check your network settings.

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.
