ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308 Reference Manual
In the single WAN case, the WAN's Internet address is either fixed IP or an FQDN if the IP
address is dynamic.
Figure B-4
Inbound Traffic to a Dual WAN Port System
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 a dual WAN port auto-rollover configuration, the WAN port's IP address will always change
when a rollover occurs. You must use an FQDN that toggles between the IP addresses of the WAN
ports (that is, WAN1 or WAN2).

Inbound Traffic: Dual WAN Ports for Load Balancing
In a dual WAN port load balancing configuration, the Internet address of each WAN port is either
fixed if the IP address is fixed or an FQDN if the IP address is dynamic (see
Figure B-6 on page
