Step 1. Enter 15 from the Main Menu.

Enter 1 to configure the Address Mapping Sets.
Step 3. Choose 1 to begin configuring this new set. Enter a Set Name, choose the Edit Action and then
select 1 from Select Rule field. Press [ENTER] to confirm.

Start IP as 192.168.1.10 (the IP address of FTP Server 1), the global Start IP as 10.132.50.1 (our
first IGA). (See Figure 4-20)
