2.4 Route Table

2.4.1 Enabling Two Networks Connected by a Router to

Access the Internet via the CS-2001

Prerequisite Setup (Note: IP addresses used as examples only)

Company A: Port 1 is set as LAN 1 (192.168.1.1, NAT routing mode) which is

connected to the LAN subnet 192.168.1.x/24. The LAN has the subnet

192.168.10.x/24 connected to Router 1 (10.10.10.1 with RIPv2). The LAN interface

connected to Router 1 is 192.168.1.252. Port 2 is set as WAN 1 (61.11.11.11) and is

connected to the Internet via the ATUR.

Port 3 is set as WAN 2 (211.22.22.22) and is connected to the Internet via the ATUR.

Company B is using Router 2 (10.10.10.2 with RIPv2) with the subnet

192.168.20.x/24 connected to it.

A leased line connects Company A’s Router 1 (10.10.10.1) with Company B’s Router

2 (10.10.10.2).
