 Chapter 10 Network Address Translation (NAT)

P-660RU-Tx User’s Guide

Configure this screen if you have multiple IP addresses from your ISP and you 
want to map them to private IP addresses on your LAN.

Note: The Address Mapping screen is available only when you select Multiple for 

the Number of IPs in the NAT screen.

Ordering your rules is important because the P-660RU-Tx applies the rules in the 
order that you specify. When a rule matches the current packet, the P-660RU-Tx 
takes the corresponding action and the remaining rules are ignored.
