Pikelet, here is what I have in my netcardconfig settings - hope this helps...

Start netcardconfig from a root konsole:

Say NO to DCHP Broadcast
Enter IP addres for lan0/eth0:
your IP address (e.g. 192.168.2.22)
Network Mask for lan0/eth0: 255.255.255.0
Broadcast Address for lan0/eth0: same as "your IP address", except last dot number is 255 (e.g. 192.168.2.255)
Default Gateway: same as "your IP address", except last dot number is 1 (e.g. 192.168.2.1)
Nameserver: I used the same as I have in "Default Gateway" setting (e.g. 192.168.2.1)

these are my netcardconfig settings, and I go through a router, which has been set to use the 192.168.2.xxx range - I also have set up in the router configurations that any IP address between the ranges of say 15 and 30 to be internal LAN systems... i.e. 192.168.2.15 through 192.168.2.30 are "local"

The above IP numbers given are _not_ real, they are just used for example.

Hope this helps,
LC
