There are four functions that NAT provides – Port Redirection, Address Mapping, DMZ
Host and Common Ports List.
Port Redirection
Port Redirection means port forwarding. It may be used to expose internal servers to the
public domain or open a specific port to internal hosts. Internet hosts can use the WAN IP
address to access internal network services, such as FTP, WWW and etc. The internal FTP
server is running on the local host addressed as 192.168.1.2. When other users send this type
of request to your network through the Internet, the router will direct these requests to an
appropriate host inside. A user can also translate the port to another port by configuration. For
example, port number with 1024 can be transferred into IP address of 192.168.1.100 of LAN.
The packet is forwarded to a specific local host if the port number matches that defined in the
table. In the Advanced group, move to NAT option and choose Port Redirection to get the
corresponding page.
