9.5.3  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.

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 P-660HWP-Dx discards all 
packets received for ports that are not specified here or in the remote 
management setup.
