Adding NAT Rules
This section explains how to create rules for each NAT flavor.
Note
You cannot edit existing NAT rules. To change a rule setup,
delete it and add a new rule with the new settings.
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 119). The
introduction to NAT on page 117 describes how the
NAPT rule
works.
1. Click the NAT tab, and then select NAT Rule Entry from the
NAT Options drop-down list.
The NAT Rule entry page displays, as shown on page 122.
2. Click to display the NAT Rule – Add page.
3. From the Rule Flavor drop-down list, select NAPT.
The page redisplays with only those fields that are appropriate
