Nat; Port Forwarding - NetComm FIBRE NF1ADV User Manual

NAT

Network address translation (NAT) is the process of modifying IP address information in IP packet headers while in transit through
the router.

Port Forwarding

Port Forwarding allows you to direct incoming traffic from the Internet side (identified by Protocol and External port) to the internal
server with a private IP address on the LAN side. The Internal port is required only if the external port needs to be converted to a
different port number used by the server on the LAN side. A maximum of 32 entries can be configured.
To add a Virtual Server, click the Add button. The following screen will display.
