FortiGate-7000E supports the FortiGate Session Life Support Protocol (FGSP) (also called standalone session sync) to synchronize sessions among up to four FortiGate-7000Es. All of the FortiGate-7000Es must be the same model and running the same firmware and must have their own network configuration (interface IPs, routing, and so on). FGSP synchronizes individual VDOM sessions.
All of the devices in an FGSP deployment must include the VDOMs to be synchronized and for each device the VDOMs must have the same firewall configuration. Multiple VDOMs can be synchronized over the same session synchronization interface. You can also distribute synchronization traffic to multiple interfaces.
The configurations should use the same interfaces on each device. If the configuration includes VLANs, the VLANs on each device should have the same names and VLAN IDs. Finally, if the configuration includes LAGs, they should have the same names and include the same interfaces on each device.
For details about FGSP for FortiOS 6.0, see: FortiOS 6.0 Handbook: FGSP.
FortiGate-7000E FGSP support has the following limitations:
- FortiGate-7000E FGSP can use the M1 or M2 interface for session synchronization. To use one these interfaces for session synchronization, you must give it an IP address and optionally set up routing for the interface as required. Ideally the session synchronization interface of each FortiGate-7000E would be on the same network and that network would only be used for session synchronization traffic. However, you can configure routing to send session synchronization traffic between networks. NAT between session synchronization interfaces is not supported.
- You can't use data interfaces for FGSP session synchronization. The FortiGate-7000E does not support using a LAG for session synchronization.
- You can use configuration synchronization to synchronize the configurations of the FortiGate-7000Es in the FGSP deployment (see Standalone configuration synchronization). You can use the M1 and M2 interfaces for configuration synchronization. You can also configure the FortiGate-7000Es separately or use FortiManager to keep key parts of the configuration, such as security policies, synchronized.
FortiGate-7000E FGSP doesn't support setting up IPv6 session filters using the
- Asymmetric IPv6 SCTP traffic sessions are not supported. These sessions are dropped.
- Inter-cluster session synchronization, or FGSP between FGCP clusters, is not supported for the FortiGate-7000E.
- FGSP IPsec tunnel synchronization is not supported.
- Fragmented packet synchronization is not supported.
