Achieving internet connectivity

I have a linux (RedHat 10) box on a Windows domain, using SAMBA. It sees,
and is seen by, the rest of my internal network, but I can't get to the
internet. Right now, my topology is as follows:

DSL box leads to a NetGear firewall/switch.
One cable leads to the first NIC in my primary domain controller (which is
running Microsoft Proxy Server).

A second NIC in the PDC leads to a hub, to which the remainder of my
machines (including the LINUX box) are connected.

My windows clients are running WIN XP, with Microsoft Proxy Client
installed.

Some years back, using the same setup, I had an earlier version of Red Hat
installed, and it worked fine -- I just set the parameters in the browser
(then Netscape) to NOT use a proxy, and somehow, it all worked itself out.

Now however, the build shippedwith Mozilla, which may or may not be a
factor.

Do I need to actually set up the browser to use a proxy, and if so, are
there any standard port numbers I have to use for the various services?

Do I need, instead, to run the LINUX box directly to the firewall/switch?
If I do this, will it still be able to participate in the local area
network?

Thanks.

There is no such thing as RedHat 10.

Please look at archives of this group for advice given to others in the
same boat. Googling archives for for "route -n" or "ifconfig" would be
a good start.
