2.3 Multiple Subnet
2.3.1 Using NAT / Routing Mode For LAN Users to
Access the Internet
Prerequisite Setup (Note: IP addresses used as examples only)
Configure port 1 as LAN1 (192.168.1.1, NAT routing mode) and connect it to the
LAN which is using the IP address range 192.168.1.x/24.
Configure port 2 as WAN1 (10.10.10.1) and connect it to the ISP router (10.10.10.2);
the IP address range distributed by the local ISP is 162.172.50.0/24.
Packets traveling to an external network via Port2, which has a private IP address of
10.10.10.1, map to the real IP address 162.172.50.1 using NAT. This allows the
signiature definition file to be updated via the Internet.
Configure port 3 as WAN2 (211.22.22.22) and connect it to the ADSL Termination
Unit Remote (ATUR) to access the Internet.
Step 1. Under System > Configuration > Multiple Subnets, set as below:
