Inbound Traffic

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:
