forwarding problem with router and SuSE 8.0

I have a LAN with a new SuSE 8.0 server which has two ethernet

eth0 with points to the LAN (
eth1 with is connected to a Linksys DSL router (which is doing NAT)

I have enabled 'ip forwarding' on the SuSE server, so all clients in
the LAN can connect to the internet.

Now I want to be able to have access to some services (especially
http) from outside the LAN, from the internet.

I setup port forwarding on my Linksys router (, so port 80
is forwarded to my SuSE Server (

This is not working. With the tcpdump utility I saw that the requests
are coming in, but there's no response to them.

I think this is not a problem of the Linksys Router because I had the
same setup with SuSE 7.2.

When I disable 'ip forwarding' I am able to access the http from
the internet, but then no clients can connect to the internet.

What am I doing wrong?

Here the routing table of my SuSE server:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface * U 0 0 0 eth0 * U 0 0 0 eth1
default UG 0 0 0 eth1
