Anyone here have any luck with PPTP through NAT with IPtables? I have recompiled my kernel with PPTP VPN MASQ support and loaded the module. I have even verified that the modules is loaded with lsmod. It tells me that it is unused. I can't seem to authenticate with PPTP to my work's VPN. I use Windows XP VPN client, with no luck. Next step is to install Freeswan and setup the client connection at the Linux box. Maybe I will have better luck doing it this way.
