Help using stunnel to tunnel through Windows 2K to an HP UX box

My company recently set up VPN capability on the Inet Server so that
certain employees could have a high speed connection to our network
over the internet.

I am running Linux and would like to use the same capability. I have
no need to work with the Windows network but I would like to be able
to connect to the HP-UX box (where I live) via the same tunnel through
the Internet server. I've looked at the stunnel man pages and a few
web sites but I'm being lazy. I'm using Red Hat 8.0 and Road Runner and
I just want to tunnel through the Internet server (a Windows 2000 machine)
and connect to another Unix box (HP-UX 11). Can anyone give me a quick
overview?

Any help much appreciated
