I logged in as root and :

yast > network devices > network card .

I check the USB option as I am using a USB router.

I enter my IP address and subnet mask. In the detailed settings:
1. I select the host name and name server
I enter the hostname and domain name feilds and the address of the DNS server.
What exactly should I enter in the domain search feilds?

2. I select the routing option,
I enter the gateway and mask. what should I enter for the destination?

IS this the way on goes about configuring the internet in SUSE? please help
