Network Planning for Dual WAN Ports

Incoming traffic from the Internet is normally discarded by the firewall unless the traffic is a 
response to one of your local computers or a service that you have configured in the Inbound Rules 
menu. Instead of discarding this traffic, you can have it forwarded to one or more LAN hosts on 
your network. 

The addressing of the firewall’s dual WAN port depends on the configuration being implemented:

The Internet IP address of the firewall’s WAN port must be known to the public so that the public 
can send incoming traffic to the exposed host when this feature is supported and enabled.

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.

The IP address range of the 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.
