What’s new in FortiOS 5.6.0                                                                                                                Introduction

What’s new in FortiOS 5.6.0

For a list of new features and enhancements that have been made in FortiOS 5.6.0, see the What’s New for FortiOS 5.6.0 document.

Special Notices

Built-In Certificate

FortiGate and FortiWiFi D-series and above have a built in Fortinet_Factory certificate that uses a 2048-bit certificate with the 14 DH group.

FG-900D and FG-1000D

CAPWAP traffic will not offload if the ingress and egress traffic ports are on different NP6 chips. It will only offload if both ingress and egress ports belong to the same NP6 chip.

FortiClient (Mac OS X) SSL VPN Requirements

When using SSL VPN on Mac OS X 10.8, you must enable SSLv3 in FortiOS.

FortiGate-VM 5.6 for VMware ESXi

Upon upgrading to FortiOS 5.6.0, FortiGate-VM v5.6 for VMware ESXi (all models) no longer supports the VMXNET2 vNIC driver.

FortiClient Profile Changes

With introduction of the Security Fabric, FortiClient profiles will be updated on FortiGate. FortiClient profiles and FortiGate are now primarily used for Endpoint Compliance, and FortiClient Enterprise Management Server (EMS) is now used for FortiClient deployment and provisioning.

The FortiClient profile on FortiGate is for FortiClient features related to compliance, such as Antivirus, Web

Filter, Vulnerability Scan, and Application Firewall. You may set the Non-Compliance Action setting to Block or Warn. FortiClient users can change their features locally to meet the FortiGate compliance criteria. You can also use FortiClient EMS to centrally provision endpoints. The EMS also includes support for additional features, such as VPN tunnels or other advanced options. For more information, see the FortiOS Handbook – Security Profiles.

Use of dedicated management interfaces (mgmt1 and mgmt2)

For optimum stability, use management ports (mgmt1 and mgmt2) for management traffic only. Do not use management ports for general user traffic.

Upgrade Information

Upgrading to FortiOS 5.6.0

FortiOS version 5.6.0 officially supports upgrading from version 5.4.3 and 5.4.4.

Security Fabric Upgrade

FortiOS 5.6.0 greatly increases the interoperability between other Fortinet products. This includes:

l FortiAnalyzer 5.6.0 l FortiClient 5.6.0 l FortiClient EMS 1.2.0 l FortiAP 5.4.2 and later l FortiSwitch 3.5.2 and later

Upgrade the firmware of each product in the correct order. This maintains network connectivity without the need to use manual steps.

Before upgrading any product, you must read the FortiOS Security Fabric Upgrade Guide.

FortiClient Profiles

After upgrading from FortiOS 5.4.0 to 5.4.1 and later, your FortiClient profiles will be changed to remove a number of options that are no longer supported. After upgrading, review your FortiClient profiles to make sure they are configured appropriately for your requirements and either modify them if required or create new ones.

The following FortiClient Profile features are no longer supported by FortiOS 5.4.1 and later:

  • Advanced FortiClient profiles (XML configuration)
  • Advanced configuration, such as configuring CA certificates, unregister option, FortiManager updates, dashboard

Banner, client-based logging when on-net, and Single Sign-on Mobility Agent l VPN provisioning l Advanced AntiVirus settings, such as Scheduled Scan, Scan with FortiSandbox, and Excluded Paths l Client-side web filtering when on-net

  • iOS and Android configuration by using the FortiOS GUI

With FortiOS 5.6.0, endpoints in the Security Fabric require FortiClient 5.6.0. You can use FortiClient 5.4.3 for VPN (IPsec, VPN, or SSL VPN) connections to FortiOS 5.6.0, but not for Security Fabric functions.

Upgrade Information                                                                                          FortiGate-VM 5.6 for VMware ESXi

FortiGate-VM 5.6 for VMware ESXi

Upon upgrading to FortiOS 5.6.0, FortiGate-VM v5.6 for VMware ESXi (all models) no longer supports the VMXNET2 vNIC driver.

Downgrading to previous firmware versions

Downgrading to previous firmware versions results in configuration loss on all models. Only the following settings are retained:

l operation mode l interface IP/management IP l static route table l DNS settings l VDOM parameters/settings l admin user account l session helpers l system access profiles.

If you have long VDOM names, you must shorten the long VDOM names (maximum 11 characters) before downgrading:

  1. Back up your configuration.
  2. In the backup configuration, replace all long VDOM names with its corresponding short VDOM name. For example, replace edit <long_vdom_name>/<short_name> with edit <short_name>/<short_ name>.
  3. Restore the configuration.
  4. Perform the downgrade.

Amazon AWS Enhanced Networking Compatibility Issue

With this new enhancement, there is a compatibility issue with older AWS VM versions. After downgrading a 5.6.0 image to an older version, network connectivity is lost. Since AWS does not provide console access, you cannot recover the downgraded image.

When downgrading from 5.6.0 to older versions, running the enhanced nic driver is not allowed. The following AWS instances are affected:

  • C3 l C4 l R3 l I2
  • M4 l D2
