Chapter 29 Network Address Translation (NAT) 278
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 169 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) in
Figure 170 on page 279.
1 Enter 15 from the main menu.
2 Enter 1 to configure the Address Mapping Sets.
3 Enter 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.
4 Select 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). (See Figure 171 on page 279).
5 Repeat the previous step for rules 2 to 4 as outlined above.
When finished, menu 15.1.1 should look like as shown in Figure 172 on page 280.
