10.5 The IP Address Mapping Screen

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.
