The filter rule: Configuring a basic rule with additional criteria
Like the basic flavor, the filter flavor translates public and private IP
addresses on a one-to-one basis. The filter flavor extends the
capability of the basic rule. Refer to “The basic Rule” on page 66 for
a general description.
You can use the filter rule if you want an address translation to
occur only when your LAN computers initiate access to specific
destinations. The destinations can be identified by their IP
addresses, server type (such as FTP or Web server), or both.
Figure 33 shows the fields used to establish a filter rule.
