Configuring The Port Forwarding Screen - ZyXEL Communications P-793H v3 User Manual

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
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 P-79X discards all packets
received for ports that are not specified here or in the remote management
setup.
Select a service from the drop-down list box.
