The odds are that you don't have the default route set up.  Do
"netstat -rn" and verify that you have a line that has "0.0.0.0" in the
first column.

The default route is normally contained in the /etc/sysconfig/network
file as the "GATEWAY=" equate.  Here's an example:

	NETWORKING=yes
	HOSTNAME=prophead.corp.publichost.com
	GATEWAY=192.168.0.1

If you don't have a default route, you can add one using this command:

	route add -default gw ip-addr-of-your-gateway

For example, to set up the default route as if it were in the network
file:

	route add -default gw 192.168.0.1
