Internet proxy server

["Bill Gilmore" <caddmasters home com>]

I am trying to configure my linux box to be a proxy server for the internet.
I have two NICs in the machine and have successfully configured SAMBA so
that the Windows 98 workstations can log into their home directories so I
know they are communicatiing.  I have setup the W98 workstations to connect
using a proxy at the eth1 ip address and port 8080, but nothing happens when
I try a URL like http://www.redhat.com.  Can someone point me in the right
direction to find specific documentation that gives me step by step
instructions for setting up the network parameters on the linux box?  Better
yet can someone tell me what those parameters are and what their values
should be?
