3. Enter the TCP/IP port number for the service that you will be using for IP mapping.
Common TCP/IP port numbers are listed below:
WWW Port 80
FTP Port 20 or 21
SMTP Port 25
POP3 Port 110
If you would like to map all services for this external IP address to a computer on
your LAN, you can enter port number 0. This means that whenever anyone accesses
your external IP address, they will automatically be “mapped” to the internal
computer that you specify, regardless of what port number they are using.
4. Enter the Internal IP address of the server to which you want to map the External IP
address.
5. Enter the port number for the service that you will be using for this IP mapping.
Click Insert to include the mapping.
6. Click OK when you have completed mapping addresses.
Note : IP Mapping function allows you to have only one port service on your LAN.
For example, if you map an external IP (16.895.1.3) to an internal IP address
(192.168.2.22 - a www server), only the internal IP address in your local network
can serve as the www.server for the external IP address.
