Inbound Rules (Port Forwarding)
When Network Address Translation (NAT) is on, the FR328S presents only one IP address to the
Internet, and outside users cannot directly address any of your local computers. However, by
defining an inbound rule you can make a local server (for example, a web server or game server)
visible and available to the Internet. The rule tells the firewall to direct inbound traffic for a
particular service to one local server based on the destination port number. This is also known as
port forwarding.
When NAT is off, all Internet addresses on your LAN are presented to the Internet and outside
users can directly address any of your local computers. For security purposes, do not turn NAT off
unless the FR328S is behind another router or firewall.
