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 72 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, the port type (which identifies it as a FTP or

Web server, for example), or both.
