Adding NAT Rules
This section explains how to create rules for the various NAT flavors.
Note

The napt rule: Translating between private and public IP addresses
Follow these instructions to create a rule for translating the private IP addresses on your LAN to 
your public IP address. This type of rule uses the NAT flavor napt, which was used in your 
default configuration. The napt flavor translates private source IP addresses to a single public IP 
address. The napt rule also translates the source port numbers to port numbers that are defined 
on the NAT Global Configuration page (see page 29).
