8.5.6 The PASS Rule
You can create a PASS rule to allow a range of IP addresses to remain untranslated
when another rule would otherwise do so.
Figure 41: NAT Rule PASS - Add
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 to NOT be subject to an existing rule, say rule ID #5, then you can create a
PASS rule with ID #1 through 4.
1 Display the NAT Rule - Add page, select PASS as the Rule Flavor and type a
Rule ID.
2 Select the interface and, if desired, a protocol that this rule applies to.
3 In the Local Address From/To fields, type the lowest and highest IP addresses
that define the range of private addresses 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 When you have completed entering all information, click the Submit button. A
page appears to confirm the change.
