8.5.6The 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.

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.

To create a PASS rule, proceed as follows:

1.Select Services > NAT > NAT Rule Entry > Add. The NAT Rule – Add page appears:

2.In the ”Rule Flavor:” dropdown list, select PASS.

3.In the “Rule ID:” field, enter an ID for the rule.

The Rule ID determines the order in which the rules are invoked (the lowest numbered rule is invoked first, and so on). In some case, two or more rules may be fined to act on the same set of IP addresses. Once a data packet matches a rule, the data is acted upon according to that rule and is not subjected to higher-numbered rules.

4.From the “IF Name:” dropdown list, select the interface on the HM210dp/di to which this rule applies.

Typically, NAT rules apply to communication between your LAN and the Internet. Because the device uses the WAN interface (named ppp-0 or eoa-0) to connect your LAN to your ISP, it is the usual IF Name selection.
