9.4.3 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.

Figure 85 Multiple Servers Behind NAT Example

9.5 Configuring Port Forwarding

Note: The Port Forwarding screen is available only when you select SUA Only in

the NAT > General screen.

If you do not assign a Default Server IP address, the ZyXEL Device discards

all packets received for ports that are not specified here or in the remote

management setup.

Click Network > NAT > Port Forwarding to open the following screen.

See Table 55 on page 162 for port numbers commonly used for particular services.
