2.2.3 Multiple Subnets
2.2.3.1 Allows Internal Users to Access the Internet via NAT or
Routing
Prerequisite Configuration (Note: The IP addresses are used as examples
only.)
Configure Port 1 as LAN 1 (192.168.1.1 in NAT Routing mode) to connect it to
the LAN subnet 192.168.1.x/24.
Configure Port 2 as WAN 1 (10.10.10.1) and connect it to the ISP router
(10.10.10.2); the subnet distributed by the local ISP is 162.172.50.0/24.
Packets traveling to an extermal network via Port 2 will carry the private IP of
10.10.10.1, which is translated into the mapped address of 162.172.50.1 for
signature definition updates.
Configure Port 3 as WAN 2 (211.22.22.22) and connect it to the ADSL
Termination Unit Remote (ATUR) to access the Internet.
