ProSafe VPN Firewall 200 FVX538 Reference Manual The Roll-over Case for Firewalls With Dual WAN Ports Rollover (Figure C-2) for the dual WAN port case is different from the single gateway WAN port case when specifying the IP address. Only one WAN port is active at a time and when it rolls over, the IP address of the active WAN port always changes. Hence, the use of a fully-qualified domain name is always required, even when the IP address of each WAN port is fixed. Dual WAN Ports (Before Rollover) Router WAN1 IP WAN1 port active X X WAN2 port inactive WAN2 IP (N/A) IP address of active WAN port changes after a rollover: o use of fully-qualified domain names always required o features requiring fixed IP address blocks not supported Dual WAN Ports (After Rollover) Router WAN1 IP (N/A) WAN1 port inactive X X WAN2 port active WAN2 IP Figure C-2 Features such as multiple exposed hosts are not supported when using dual WAN port rollover because the IP addresses of each WAN port must be in the identical range of fixed addresses. The Load Balancing Case for Firewalls With Dual WAN Ports Load balancing (Figure C-3) for the dual WAN port case is similar to the single WAN port case when specifying the IP address. Each IP address is either fixed or dynamic based on the ISP: fullyqualified domain names must be used when the IP address is dynamic and are optional when the IP address is static.
