Special Notices

• FortiGuard Security Rating Service l FortiGate hardware limitation l CAPWAP traffic offloading
• FortiClient (Mac OS X) SSL VPN requirements l Use of dedicated management interfaces (mgmt1 and mgmt2) l Using FortiAnalyzer units running older versions on page 8

FortiGuard Security Rating Service

Not all FortiGate models can support running the FortiGuard Security Rating Service as a Fabric “root” device. The following FortiGate platforms can run the FortiGuard Security Rating Service when added to an existing Fortinet Security Fabric managed by a supported FortiGate model: l FGR-30D l FGR-35D l FGT-30E l FGT-30E-MI l FGT-30E-MN l FGT-50E l FGT-51E l FGT-52E l FWF-30E l FWF-30E-MI l FWF-30E-MN l FWF-50E-2R l FWF-50E l FWF-51E

FortiGate 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. l Spanning tree loops may result depending on the network topology.

Special Notices                                                                                                                                                          7

FG-92D does 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 global set hw-switch-ether-filter <enable | disable>

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.

CAPWAP traffic offloading

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. The following models are affected: l FG-900D l FG-1000D l FG-2000E l FG-2500E

FortiClient (Mac OS X) SSL VPN requirements

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

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.

 

Special Notices

Using FortiAnalyzer units running older versions

When using FortiOS 6.2.0 with FortiAnalyzer units running 5.6.5 or lower, or 6.0.0-6.0.2, FortiAnalyzer might report increased bandwidth and session counts if there are sessions that last longer than two minutes.

For accurate bandwidth and session counts, upgrade the FortiAnalyzer unit to 5.6.6 or higher, or 6.0.2 or higher.

Upgrade Information

Supported upgrade path information is available on the Fortinet Customer Service & Support site.

To view supported upgrade path information:

1. Go to https://support.fortinet.com.
2. From the Download menu, select Firmware Images.
3. Check that Select Product is FortiGate.
4. Click the Upgrade Path tab and select the following:

l Current Product l Current FortiOS Version l Upgrade To FortiOS Version

5. Click Go.

FortiClient Endpoint Telemetry license

Starting with FortiOS 6.2.0, the FortiClient Endpoint Telemetry license is deprecated and as a result there are two upgrade scenarios:

• Customers using only a FortiGate device in FortiOS 6.0 to enforce compliance must install FortiClient EMS 6.2.0 and purchase a FortiClient Security Fabric Agent License.
• Customers using both a FortiGate device in FortiOS 6.0 and FortiClient EMS running 6.0 for compliance enforcement, must upgrade both the FortiGate device to FortiOS 6.2.0, FortiClient to 6.2.0, and FortiClient EMS to 6.2.0.

Fortinet Security Fabric upgrade

FortiOS 6.2.0 greatly increases the interoperability between other Fortinet products. This includes:

l FortiAnalyzer 6.2.0 l FortiClient EMS 6.2.0 l FortiClient 6.2.0 l FortiAP 5.4.4 and later l FortiSwitch 3.6.9 and later

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

If Security Fabric is enabled, then all FortiGate devices must be upgraded to 6.2.0. When Security Fabric is enabled in FortiOS 6.2.0, all FortiGate devices must be running FortiOS 6.2.0.

 

Minimum version of TLS services automatically changed

For improved security, FortiOS 6.2.0 uses the ssl-min-proto-version option (under config system global) to control the minimum SSL protocol version used in communication between FortiGate and third-party SSL and TLS services.

When you upgrade to FortiOS 6.2.0 and later, the default ssl-min-proto-version option is TLS v1.2. The following SSL and TLS services inherit global settings to use TLS v1.2 as the default. You can override these settings.

l Email server (config system email-server) l Certificate (config vpn certificate setting) l FortiSandbox (config system fortisandbox) l FortiGuard (config log fortiguard setting) l FortiAnalyzer (config log fortianalyzer setting) l LDAP server (config user ldap) l POP3 server (config user pop3)

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 admin user account l session helpers l system access profiles

Amazon AWS enhanced networking compatibility issue

With this enhancement, there is a compatibility issue with older AWS VM versions. After downgrading a 6.2.0 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 6.2.0 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

FortiLink access-profile setting

The new FortiLink local-access profile controls access to the physical interface of a FortiSwitch that is managed by FortiGate.

After upgrading FortiGate to 6.2.0, the interface allowaccess configuration on all managed FortiSwitches are overwritten by the default FortiGate local-access profile. You must manually add your protocols to the localaccess profile after upgrading to 6.2.0.

To configure local-access profile:

config switch-controller security-policy local-access edit [Policy Name] set mgmt-allowaccess https ping ssh set internal-allowaccess https ping ssh

next

end

To apply local-access profile to managed FortiSwitch:

config switch-controller managed-switch edit [FortiSwitch Serial Number] set switch-profile [Policy Name] set access-profile [Policy Name]

next

end

FortiGate VM with V-license

This version allows FortiGate VM with V-License to enable split-vdom.

To enable split-vdom:

config system global set vdom-mode [no-vdom | split vdom] end

FortiGuard update-server-location setting

The FortiGuard update-server-location default setting is different between hardware platforms and VMs. On hardware platforms, the default is any. On VMs, the default is usa.

On VMs, after upgrading from 5.6.3 or earlier to 5.6.4 or later (including 6.0.0 or later), update-server-location is set to usa.

If necessary, set update-server-location to use the nearest or low-latency FDS servers.

To set FortiGuard update-server-location:

config system fortiguard set update-server-location [usa|any]

end

FortiView widgets

FortiView widgets have been rewritten in 6.2.0. FortiView widgets created in previous versions are deleted in the upgrade.

Limitations

Citrix XenServer limitations

The following limitations apply to Citrix XenServer installations:

• XenTools installation is not supported.
• FortiGate-VM can be imported or deployed in only the following three formats:
• XVA (recommended)
• VHD l OVF
• The XVA format comes pre-configured with default configurations for VM name, virtual CPU, memory, and virtual NIC. Other formats will require manual configuration before the first power on process.

Open source XenServer limitations

When using Linux Ubuntu version 11.10, XenServer version 4.1.0, and libvir version 0.9.2, importing issues may arise when using the QCOW2 format and existing HDA issues.
