The pass rule: Allowing specific addresses to pass through
untranslated
You can create a pass rule to allow a range of IP addresses to
remain untranslated when another rule would otherwise do so
Figure 27. NAT Rule – Add Page (pass Flavor)
The pass rule must be assigned a rule ID that is a lower number
than the ID assigned to the rule it is intended to pass. In you want a
specific IP address or range of addresses to not be subject to an
existing rule, say rule ID #5, then you can create a pass rule with ID
#1 through #4.
Follow these instructions to add a pass rule (see steps 1-4 under
"The napt rule" on page 58 for detailed instructions corresponding to
steps 1 and 2 below):
1. Display the NAT Rule – Add Page, select
PASS
as the Rule
Flavor, and enter a Rule ID.
2. Select the interface on which this rule will be effective.
3. In the Local Address From and Local Address To fields, type
the lowest and highest IP addresses that define the range of
private address you want to be passed without translation.
If you want the pass rule to act on only one address, type that
address in both fields.
4. Follow steps 7-12 under "The napt rule" on page 58 to
submit your changes.
