dhcp

okay i am running SuSE 7.2(FINALLY thanx gontran and EBo) and so far all
i have done is ran yast2 and setup the NIC and i ran the hostname/dns
utility and checked the box that said use dhcp to set the hostname. And
i tried pinging stuff starting with this computer which it is hooked up
to on a network and it worked...the i tried pinging the gateway that
qwesy gave us and that worked...but i cant get outside to the internet.
If anyone knows whats goin on and can help i would appreciate it MUCHO!
thanx
