3 Network cards in one PC, Routing Problem

Hi

i set up an Suse 9.0 Server(Router). there are 3 networkcards 1 is
connected to my DSL Modem 1(eth1 192.168.1.0), the other is connected to
my LAN (eth0 in 192.168.0.0) und the third one is DLINK DWL 520 Wlan
(wlan0 in 192.168.2.0) Card. I formed a small ad-hoc network where 2
Laptops are connected. the routing between DSL(eth1) und LAN(eth0) is
working. it is not possible to ping the laptop from the server and
back(laptop -> server). the link between laptop and server is
established, if only the wirless network cards are enabled, you can ping
.. it seems that it is a routing problem. i tried around without success.

the wireless configuration is working, i tried it succesful on my campus.

here is the routing of my server and laptop and the ifconfigs
the eth0 in my laptop should not be used. only the wlan0.

i hope someone is able to help me.

thx

numbers look good, but private subnets are by design non routed,
So look at firewall rules, or DNS settings on the server first.

thx to you, i figured out, that it was the firewall and the maquerading.
the wlan0 was not configured to be an internal device. Setting
SuSEFirewall2 to quickmode and evrything was fine. I put the wlan0
device as internal doesn't change anything. but I'm confident to find
the problem and i will post it here.

regards
