Map the other outgoing LAN traffic to IGA3 (Many : 1 mapping).

You also map your third IGA to the web server and mail server on the LAN. Type Server allows you to specify multiple servers, of different types, to other computers behind NAT on the LAN.

The example situation looks somewhat like this:

Figure 145 NAT Example 3

In this case you need to configure Address Mapping Set 1 from Menu 15.1 - Address Mapping Sets. Therefore you must choose the Full Feature option from the Network Address Translation field (in menu 4 or menu 11.3) inFigure 146 on page 241.

1Enter 15 from the main menu.

2Enter 1 to configure the Address Mapping Sets.

3Enter 1 to begin configuring this new set. Enter a Set Name, choose the Edit Action and then enter 1 for the Select Rule field. Press [ENTER] to confirm.

4Select Type as One-to-One(direct mapping for packets going both ways), and enter the local 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). (SeeFigure 147 on page 241).

5Repeat the previous step for rules 2 to 4 as outlined above.

When finished, menu 15.1.1 should look like as shown inFigure 148 on page 242.
