Chapter 11 Network Address Translation (NAT)

VMG5313-B10A/-B30A Series User’s Guide

182

NAT

In the simplest form, NAT changes the source IP address in a packet received from a subscriber 
(the inside local address) to another (the inside global address) before forwarding the packet to the 
WAN side. When the response comes back, NAT translates the destination address (the inside 
global address) back to the inside local address before forwarding it to the original inside host.

Port Forwarding

A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, 
that you can make visible to the outside world even though NAT makes your whole inside network 
appear as a single computer to the outside world.

Finding Out More

See 

Section 11.9 on page 193

 for advanced technical information on NAT.

11.2  The Port Forwarding Screen 

Use the 

Port Forwarding

 screen to forward incoming service requests to the server(s) on your 

local network.

You may enter a single port number or a range of port numbers to be forwarded, and the local IP 
address of the desired server. The port number identifies a service; for example, web service is on 
port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can 
support more than one service (for example both FTP and web service), it might be better to 
specify a range of port numbers. You can allocate a server IP address that corresponds to a port or 
a range of ports.

The most often used port numbers and services are shown in 

Appendix D on page 383

. Please refer 

to RFC 1700 for further information about port numbers. 

Note: Many residential broadband ISP accounts do not allow you to run any server 

processes (such as a Web or FTP server) from your location. Your ISP may 

periodically check for servers and may suspend your account if it discovers any 

active services at your location. If you are unsure, refer to your ISP.

Configuring Servers Behind Port Forwarding (Example)

Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (

A

 in the example), 

port 80 to another (

B

 in the example) and assign a default server IP address of 192.168.1.35 to a 

third (

C

 in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. 

The NAT network appears as a single host on the Internet.
