How to Configure Multiple Internal Networks

[avrkvarma]

Hi
My network senario.

Eth0  : External Network

Eth 1 : 192.168.1.9/24   (1.0 network has another firewall with 1.5 gateway)

Eth 2 : 192.168.2.1/24

Now, I require all my 2.0 network should access 1.0 network. No need to access 1.0 network to 2.0 network. If not, both can access.
Please Guide me How.

Thank You

First:

Eth 1 : 192.168.1.9/24   (1.0 network has another firewall with 1.5 gateway)

you realize that 192.168.1.0 is also on the 192.168.1.9/24 subnet?

Second: if you want the 192.168.2.x/24 subnet can reach the 192.168.1.x/24 subnet, you should add a route for 192.168.2.x/24 subnet to 192.168.1.x/24 subnet.
