Inbound Traffic To Dual Wan Port Systems - NETGEAR FVX538v2 - ProSafe VPN Firewall Dual WAN Reference Manual

ProSafe VPN Firewall 200 FVX538 Reference Manual
In the single WAN case, the WAN's Internet address is either fixed IP or a fully-qualified domain
name if the IP address is dynamic.

Inbound Traffic to Dual WAN Port Systems

The IP address range of the VPN firewall's WAN port must be both fixed and public so that the
public can send incoming traffic to the multiple exposed hosts when this feature is supported and
enabled.
Inbound Traffic: Dual WAN Ports for Improved Reliability
In the dual WAN port case with rollover, the WAN's IP address will always change at rollover. A
fully-qualified domain name must be used that toggles between the IP addresses of the WAN ports
(that is, WAN1 or WAN2).
