I have a problem with my suse server. All of the MS computers from same network (subnet) could pass ISP ruter (Cisco), but Suse server could not communicate with the outside world. I have checked with ISP administrator and he has assured me that there is no any access list to stop it from passing.

I have tried my best to make it going but it seems to me, that there is problem somewhere else. Firewall is switched off. DNS is OK as you might see.
The message “Hint: you may set mandatory devices in /etc/sysconfig/network/config” is what puzzles me.
What else can I do to check my network interface with OpenSuse (10.2)?
How are you trying to access the outside world? All I see is a really
weird bit of traceroute output. What do you get form ping? wget?
curl? ftp? I assume you can access anything on the 192.168.0.1
(gateway) even though you can’t get past it, right?
Good luck.
