12.3 The Address Mapping Screen
Ordering your rules is important because the Router applies the rules in the order that you specify.
When a rule matches the current packet, the Router takes the corresponding action and the
remaining rules are ignored.
This screen is avaliable only when you select
NAT Full Feature on
in the
General
screen. To change
your Router’s address mapping settings, click
Network Setting > NAT > Address Mapping
.
