IP Tables NAT of Windows Login?

[Aaron Grewell]

I've tried to do this a couple of different ways.  The only  way that has been 
successful so far is to use pptp tunneling.  You can either tunnel directly 
to the server you want to login to, or set up the linux pptpd on your 
firewall and tunnel to the firewall.
