You have two choices:

A proxy firewall or a IP masquerading firewall.
The first is quite easy, the second is even easier.
Both require recompiling the kernel.

You need to read the Proxy Server / Firewall howto,
available from sunsite.unc.edu.

If you plan to use IP masqurading then you need the IP Masq. mini
howto, also available from sunsite. You probably have both of these
howtos installed on your linux box under /usr/doc/HOWTO and
/usr/doc/HOWTO/mini

This takes a bit of fiddling but it does work in the end, i have used
both methods, I started with IP Masq. which produced a fast and
pleasingly simple gateway. I have now "upgraded" to a proxy firewall
gateway and am using the TIS firewall toolkit.

Good luck and have fun...

P.S. Win 95 with IE 3 works reliably and well. If you use IP masq.
then you need to put in the IP address of your linux bos as the
gateway. If you use a proxy then in IE3 go to options and connection,
tick connect through proxy and place the address of your server
in there.
