Wen,
Have you made a static route on the firewall to your other internal network? I can see you have a route on the client for the firewall-lan probably pointing at the router. You also need a similar route pointing in the other direction on the firewall.

On the client you can normally make a default gw pointing to the router instead of having a route for each network, unless you have several routers located on the same subnet.

Having a rule with Any with telnet access to the firewall is not recommended, but will work. Once you connect the firewall to the internet I suggest you restrict this rule, not allowing external hosts to connect to your firewall this way.

Lars
