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.

DESCRIPTION
Default Server Setup
Default Server
In addition to the servers for specified services, NAT supports a default server. A
default server receives packets from ports that are not specified in this 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.
