PPTPD: System hangs when launching a connection

Hi,

recently I tried to set up a VPN gateway with poptop, but without success...
When I try to launch a connection from Win2k the system freezes while checking the username and password. All i can do then is hard-reset the computer.
I tried several Tutorials and howtos but without success...
Could it be possible that the system hangs because I try to connect from within the local network instead of trying to access the gateway from the internet?
What could be the reason for the crash? The pptpd binary? The kernel module? A wrong config?
And how can I start the pptpd, because I can't find any start-/stop scripts in /etc/init.d? Should I create one or is there an easy other way to launch it automatically at startup?

Please give me some hints, I'm very depressed...

Mine has been working flawlessly for a while now. Running gentoo sources 2.4.20r6 the key is to not load any pptp related iptables modules (I think the pptp conntrack module was the crucial one, but pptp NAT should also be avoided).

This of course will disable you from having a pptp server and connect to external pptp servers at the same time (provided the same machine is also a NATing firewall).

I read someplace that if you patch the kernel yourself pptp and the NAT modules work fine.
