4. Enter a Rule ID.
The Rule ID determines the order in which rules are
invoked (the lowest numbered rule is invoked first, and
so on). If you define two or more rules that act on the
same set of IP addresses, be sure to assign the Rule ID so
that the higher priority rules are invoked first. It is
recommended that you specify rule IDs as multiples of 5
or 10 so that, in the future, you can insert a rule
between two existing rules.
Once a data packet matches a rule, the data is acted
upon according to that rule and is not subjected to
higher-numbered rules.
5. From the IFName drop-down list, select the interface on the
device to which this rule applies.
Typically, NAT rules are used for communication between
your LAN and the Internet. Because the device uses the
WAN interface (which may be named ppp-0, eoa-0, or
ipoa-0) to connect your LAN to your ISP, it is the usual
IFName selection.
6. In the Local Address From field and Local Address To fields,
type the starting and ending IP addresses, respectively, of
the range of private address you use on your network that
you want to be translated.
You can specify that data from all LAN addresses should
be translated by typing 0 (zero) in each From field and
255 in each To field. Or, type the same address in both
fields if the rule only applies to one LAN computer.
7. In the Global Address From and Global Address To fields,
type the public IP address assigned to you by your ISP.
If you have multiple WAN interfaces, in both fields type
the IP address of the interface to which this rule applies.
This rule will not be enforced for data that arrives on
other WAN interfaces.
If you have multiple WAN interfaces and want the rule to
be enforced on a range of them, type the starting and
ending IP addresses of the range.
8. Click .

Configuration table.
10. Ensure that the Enable radio button is selected, and then
