type the starting and ending address that identify the pool of 
public IP addresses that the private addresses should be 
translated to. Or, type the same address in both fields (if you 
also specified a single address in step 4). 

6.  Follow steps 7-12 under "The napt rule" on page 68 to 

submit your changes. 

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 73 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 35 shows the fields used to establish a filter rule.
