SuSE 9 - Router Configuration

Here you can find a picture of my network and the configurations on every interface:
URL

I am trying to configure SuSE 9 as a router.
From the workstaion in the picture I can ping every interface of the router! (10.1.0.1, 10.0.0.1, 81.196.96.2), but I can''t reach the router's gateway (81.196.96.1). For the moment I am only trying to get the routing process working, then I will try to find out how to configure the NAT.
At this point I have this configuration on my router:

Kernel IP routing table

81.196.96.0__0.0.0.0_______255.255.255.192___U___0___0___0__ eth0

If you can't access your gateway from Linux, it means you are not linked properly to it. Make sure you can ping .1 gateway. You may benefit from -I option in ping to set the source address to 81.196.96.2

Hope this helps.

personaly I think maybe your linux router is working fine and your default gateway router that you are trying to ping does not have a route back to the 10.1.0.0/16 network. In other words make sure your internet router has a static route for the 10.1.0.0/16 network pointing back to the linux box so it can reply back to your ICMP request.
