Configuring NAT

EN/LZT 108 6492 R2 - October 2003

1. Select Services > NAT > NAT Rule Entry > Add. The NAT Rule –

Add page appears:

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

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.

5. Select a “Protocol:” to which this rule applies, or select ALL if the

rule applies to all data.

6. In the “Local Address From/To:” fields, type the starting and

ending IP addresses that identify the range of private addresses you
want to be translated. Or, type the same IP address in both fields.
If you specify a range, each address will be translated in sequence
to a corresponding address in a range of global addresses (which
you specify in the next step).
