The purpose of the FQDN in this case is to toggle the domain name of the gateway firewall between the IP addresses of the active WAN port (that is, WAN1 and WAN2) so that the remote VPN client can determine the gateway IP address to establish or reestablish a VPN tunnel.

VPN Road Warrior: Dual-Gateway WAN Ports for Load Balancing

In a dual WAN port load balancing gateway configuration, the remote VPN client initiates the VPN tunnel with the appropriate gateway WAN port (that is, port WAN1 or WAN2 as necessary to balance the loads of the two gateway WAN ports) because the IP address of the active WAN port is not known in advance. The selected gateway WAN port needs to function as the responder.

Figure 369.

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