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 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 step
4).
4 In the Global Address From/To fields, type the starting and ending IP address
that identify the pool of public IP addresses to which to translate your private
addresses. Or, type the same IP address in both fields (if you also specified a
single address in step 3).
5 When you have completed entering all information, click the Submit button. A
page appears to confirm the change.
6 Click Close to return to the NAT Configuration page. The new rule should now
be displayed in the NAT Rule table.

permanent storage.

on a one-to-one basis. The FILTER flavor extends the capability of the BASIC rule.
