Help on Networking

I hope that someone can help me. I'm actually worse than a newbie to
RH 8.0
I have installed RH 8.0 onto a machine as a server. It is connected to
my (please don't hate me) Windows network. I
I can ping anything on my network but I can't seem to configure a
gateway and DNS settings to be able to use my Zywall 10 , which is an
ADSL router.

My gateway ip is 192.120.120.209 and I have two settings for primary
and secondary DNS ip which are 194.125.133.10 & 194.125.133.11 .
Can any one point me to a good link to do this ?

tks
