Planning for Inbound Traffic

Incoming traffic from the Internet is normally discarded by the VPN firewall unless the traffic is
a response to one of your local computers or a service for which you have configured an
inbound rule. Instead of discarding this traffic, you can configure the VPN firewall to forward it
to one or more LAN hosts on your network.
The addressing of the VPN firewall's dual WAN port depends on the configuration being
implemented.
