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).
