Help need!! got networkproblems

Hi, everyone!

I've got a problem with my server, which I normally use as a router for 2
subnets. The first subnet 192.168.0.0 nm 255.255.255.0 is working fine at
eth0 192.168.0.1. But the second subnet 192.168.1.0 nm 255.255.255.0 at
eth1 192.168.1.1 drives me crazy......I'm able perform a ping on
192.168.1.1 without any problems, but I'm not able to ping any other
machine in that subnet.
ifconfig gives me almost the same output for both interfaces(not IP, etc.)
except eth1 has collisions. And tcpdump shows me some arp traffic from a
client.

So can anybody help me solving that problem??....or knows the answer to my
question?

Below are the outputs of route, netstat and ifconfig

bye
Jens
