Using the NAT Port Mapping feature, remote users can access different
servers on your local network using your single public IP address.
Remote users accessing services such as web or FTP at your local site
thorugh your public IP address, are redirected (mapped) to other local
server IP addresses and TCP/UDP port numbers. For example, if you set
Type/Public Port to TCP/80 (HTTP or web) and the Private IP/Port to
192.168.7.9/80, then all HTTP requests from outside users forwarded to
192.168.7.9 on port 80. Therefore, by just using your external IP address
provided by your ISP, Internet users can access the services they need at
the local addresses to which you redirect them.
The more common TCP service port numbers include: HTTP: 80, FTP: 21,
Telnet: 23, and SSH: 22.

The following parameters are displayed on this page:
Private IP

can be set by selecting a PC from the DHCP client list.
Use Client List
Allows the Private IP to be selected from the DHCP
client list.
Private Port
Specifies the TCP/UDP port number used on the local
server for the service. (Range: 1-65535)
Public Port
Specifies the public TCP/UDP port used for the service on
the WAN interface. (Range: 1-65535)
Services
Specifies port numbers for some of the more common
services. (Options: FTP, SSH, Telnet, SMTP, HTTP, HTTPS)
