The IP address of the gateway WAN ports can be either fixed or dynamic. If an IP address is dynamic, you must use a FQDN. If an IP address is fixed, an FQDN is optional.

VPN Gateway-to-Gateway: Dual Gateway WAN Ports for Improved Reliability

In a configuration with two dual-WAN port VPN gateways that function in auto-rollover mode, either of the gateway WAN ports at one end can initiate the VPN tunnel with the appropriate gateway WAN port at the other end as necessary to balance the loads of the gateway WAN ports because the IP addresses of the WAN ports are known in advance. In this example (see

Figure B-14), port WAN_A1 is active and port WAN_A2 is inactive at Gateway A; port WAN_B1 is active and port WAN_B2 is inactive at Gateway B.

Figure B-14

The IP addresses of the gateway WAN ports can be either fixed or dynamic, but you must always use a FQDN because the active WAN ports could be either WAN_A1, WAN_A2, WAN_B1, or WAN_B2 (that is, the IP address of the active WAN ports is not known in advance).
