NAT64 and NAT66 session failover
The FortiGate Clustering Protocol (FGCP) supports IPv6, NAT64, and NAT66 session failover. If session pickup is enabled, these sessions are synchronized between cluster members and, after an HA failover, the sessions will resume with only minimal interruption.
NAT46 is used to translate IPv4 addresses to IPv6 addresses so that a client on an IPv4 network can communicate transparently with a server on an IPv6 network.
To enable NAT46, use the following CLI command:
config firewall vip46
Security policies for NAT46 can be configured from the web-based manager. For these options to appear in the web-based manager, this feature must be enabled using System > Feature Select. You can then configure the policies under Policy & Objects > NAT46 Policy.
NAT46 policies and can also be configured from the CLI using the following command:
config firewall policy46
