No internet connection

After upgrading from RH 9.0 to Fedora Core 1 my internet connection is not working. eth0 is working, and I can ping localhost and my static IP address as well as domain name. When I try to fire up Mozilla I can not get a connection. This is what I get when running ifconfig:

eth0 Link encap:Ethernet HWaddr 00:20:ED:30:0E:8A

Any suggestions greatly appreciated.
