What’s new in FortiOS 5.4.6

For a detailed list of new features and enhancements that have been made in FortiOS 5.4.6, see the What’s New forFortiOS 5.4.6 document available in the Fortinet Document Library.

Special Notices

Built-In Certificate

FortiGate and FortiWiFi D-series and above have a built in Fortinet_Factory certificate with an RSA 2048-bit key; and FortiOS supports DH group 14 for key-exchange.

Default log setting change

For FG-5000 blades, log disk is disabled by default. It can only be enabled via CLI. For all 2U & 3U models (FG-3600/FG-3700/FG-3800), log disk is also disabled by default. For all 1U models and desktop models that supports SATA disk, log disk is enabled by default.

FortiAnalyzer Support

In version 5.4, encrypting logs between FortiGate and FortiAnalyzer is handled via SSL encryption. The IPsec option is no longer available and users should reconfigure in GUI or CLI to select the SSL encryption option as needed.

Removed SSL/HTTPS/SMTPS/IMAPS/POP3S

SSL/HTTPS/SMTPS/IMAPS/POP3S options were removed from server-load-balance on low end models below FG-100D except FG-80C and FG-80CM.

FortiGate and FortiWiFi-92D Hardware Limitation

FortiOS 5.4.0 reported an issue with the FG-92D model in the Special Notices > FG-92D High Availability in Interface Mode section of the release notes. Those issues, which were related to the use of port 1 through 14, include:

• PPPoE failing, HA failing to form l IPv6 packets being dropped l FortiSwitch devices failing to be discovered
• Spanning tree loops may result depending on the network topology

FG-92D and FWF-92D do not support STP. These issues have been improved in FortiOS 5.4.1, but with some side effects with the introduction of a new command, which is enabled by default:

config system global set hw-switch-ether-filter <enable | disable>

FG-900D and FG-1000D                                                                                                               Special Notices

When the command is enabled:

• ARP (0x0806), IPv4 (0x0800), and VLAN (0x8100) packets are allowed l BPDUs are dropped and therefore no STP loop results l PPPoE packets are dropped l IPv6 packets are dropped l FortiSwitch devices are not discovered l HA may fail to form depending the network topology

When the command is disabled:

• All packet types are allowed, but depending on the network topology, an STP loop may result

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.

FG-3700DX

CAPWAP Tunnel over the GRE tunnel (CAPWAP + TP2 card) is not supported.

FortiGate units managed by FortiManager 5.0 or 5.2

Any FortiGate unit managed by FortiManager 5.0.0 or 5.2.0 may report installation failures on newly created VDOMs, or after a factory reset of the FortiGate unit even after a retrieve and re-import policy.

FortiClient Support

Only FortiClient 5.4.1 and later is supported with FortiOS 5.4.1 and later. Upgrade managed FortiClients to 5.4.1 or later before upgrading FortiGate to 5.4.1 or later.

Consider the FortiClient license before upgrading. Full featured FortiClient 5.2 and 5.4 licenses will carry over into FortiOS 5.4.1 and later. Depending on your organization’s needs, you might need to purchase a FortiClient EMS license for endpoint provisioning. Contact your sales representative for guidance on the appropriate licensing for your organization.

The perpetual FortiClient 5.0 license (including the 5.2 limited feature upgrade) will not carry over into FortiOS 5.4.1 and later. You need to purchase a new license for either FortiClient EMS or FortiGate. A license is compatible with 5.4.1 and later if the SKU begins with FC-10-C010.

 

Special Notices                                                                                FortiClient (Mac OS X) SSL VPN Requirements

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 5.4 for VMware ESXi

Upon upgrading to FortiOS 5.4.6, FortiGate-VM v5.4 for VMware ESXi (all models), no longer supports the VMXNET2 vNIC driver.

FortiClient Profile Changes

With introduction of the Cooperative Security Fabric in FortiOS, 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.

In the FortiClient profile on FortiGate, when you set the Non-Compliance Action setting to Auto-Update, the

FortiClient profile supports limited provisioning for FortiClient features related to compliance, such as AntiVirus,

Web Filter, Vulnerability Scan, and Application Firewall. When you set the Non-Compliance Action setting to Block or Warn, you can also use FortiClient EMS to provision endpoints, if they require additional other features, such as VPN tunnels or other advanced options. For more information, see the FortiOS Handbook – Security

Profiles.

When you upgrade to FortiOS 5.4.1 and later, the FortiClient provisioning capability will no longer be available in FortiClient profiles on FortiGate. FortiGate will be used for endpoint compliance and Cooperative Security Fabric integration, and FortiClient Enterprise Management Server (EMS) should be used for creating custom FortiClient installers as well as deploying and provisioning FortiClient on endpoints. For more information on licensing of EMS, contact your sales representative.

FortiPresence

FortiPresence users must change the FortiGate web administration TLS version in order to allow the connections on all versions of TLS. Use the following CLI command.

config system global set admin-https-ssl-versions tlsv1-0 tlsv1-1 tlsv1-2

end

Log Disk Usage

Users are able to toggle disk usage between Logging and WAN Optimization for single disk FortiGates.

To view a list of supported FortiGate models, refer to the FortiOS 5.4.0 Feature Platform Matrix.

SSL VPN setting page                                                                                                                   Special Notices

SSL VPN setting page

The default server certificate has been changed to the Fortinet_Factory option. This excludes FortiGateVMs which remain at the self-signed option. For details on importing a CA signed certificate, please see the How to purchase and import a signed SSL certificate document.

Upgrade Information

Upgrading to FortiOS 5.4.6

FortiOS version 5.4.6 officially supports upgrading from version 5.4.4 and later, and 5.2.10 and later.

When upgrading from a firmware version beyond those mentioned in the Release Notes, a recommended guide for navigating the upgrade path can be found on the Fortinet documentation site.

There is a separate version of the guide describing the safest upgrade path to the latest patch of each of the supported versions of the firmware. To upgrade to this build, go to FortiOS 5.4 Supported Upgrade Paths.

Upgrading to FortiOS 5.6.0

Cooperative Security Fabric Upgrade

FortiOS 5.4.1 and later greatly increases the interoperability between other Fortinet products. This includes:

• FortiClient 5.4.1 and later l FortiClient EMS 1.0.1 and later l FortiAP 5.4.1 and later l FortiSwitch 3.4.2 and later

The upgrade of the firmware for each product must be completed in a precise order so the network connectivity is maintained without the need of manual steps. Customers must read the following two documents prior to upgrading any product in their network:

• Cooperative Security Fabric – Upgrade Guide
• FortiOS 5.4.x Upgrade Guide for Managed FortiSwitch Devices

This document is available in the Customer Support Firmware Images download directory for FortiSwitch 3.4.2.

FortiGate-VM 5.4 for VMware ESXi                                                                                          Upgrade Information

FortiGate-VM 5.4 for VMware ESXi

Upon upgrading to FortiOS 5.4.6, FortiGate-VM v5.4 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

When downgrading from 5.4 to 5.2, users will need to reformat the log disk.

Amazon AWS Enhanced Networking Compatibility Issue

Due to this new enhancement, there is a compatibility issue with older AWS VM versions. After downgrading a 5.4.1 or later image to an older version, network connectivity is lost. Since AWS does not provide console access, you cannot recover the downgraded image.

Downgrading to older versions from 5.4.1 or later running the enhanced nic driver is not allowed. The following AWS instances are affected:

• C3 l C4 l R3 l I2
• M4 l D2
