Configuring Network Address Translation
2. Select the interface ([IF Name:]) on which this rule will be
effective.
3. Select a [Protocol:] to which this rule applies, or choose
[ANY]. This selection specifies which type of Internet
communication will be subject to this translation rule. You can
select [ANY] if the rule applies to all data. Or, select [TCP],
[UDP], [ICMP], or a number from [1-255] that represents the
Internet Assigned Numbers Authority (IANA)-specified
protocol number.
4. In the [Local Address From:] and [Local Address To:] fields,
type the starting and ending IP addresses that identify the
range of private addresses you want to have translated.
Or, type the same 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 step 5).
The address (or range of addresses) should correspond
to a private address (or addresses) already in use on
your network. These may be assigned statically to your
PCs or assigned dynamically using DHCP, as discussed
in the Quick Start.
5. In the [Global Address From:] and [Global Address To:] fields,
type the starting and ending address that identify the range
of public IP addresses to translate your private addresses to.
Or, type the same address in both fields (if you also specified
a single address in step 4).
6. In the [Destination Address From:] and [Destination Address
To:] fields, specify a destination address (or range) if you want
this rule to apply only to outbound traffic to the address
(or range).
