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.

The Address Mapping screen is available only when you select Multiple for
the Number of IPs in the NAT screen.

you specify. When a rule matches the current packet, the ZyXEL Device takes the
corresponding action and the remaining rules are ignored.
