I had to change the IP for my server box to 192.168.0.2 from 192.168.0.1 because the modem wants to be 192.168.0.1.
I added a 2nd NIC as 192.168.0.3.
I've setup the gateway on all my boxes as 192.168.0.2
I can ping everything on my internal network, but everything outside gets errors (unable to find host)
Try pinging outside your network, using the IP address, instead of host name.
The resolver is now working, and both IP and name now return the same error: Destination Host Unreachable.
I've looked at the NAT stuff suggested by another. Shouldn't that be setup automatically by the yast firewall config??
Did you enable masquerading by checking YaST->Security and Users->Firewall->Forward Traffic and Do Masquerading? That should give you a basic NAT/Masquerading setup. Can you ping the internet and each of the internal boxes from the server? This would verify that the connections are good. Jeff
