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. If you want
a specific IP address or range of addresses not to 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 66 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.
