I've tried setting up the m0n0wall PPTP server as well, I got the exact 
same errors on the Windoze XP clients. I figured it just doesn't work 
with windows so I created an internal vpn server and forwarded the ports 
to it instead.  I've read the tutorials on getting windows to work with 
the pptp of m0n0wall, but even with a direct internet connection and ip 
address, it still gets the same error you get with "732, could not agree 
on PPP control protocols".  I gave up on it due to time restraints, but 
if anyone figures out how to get windows clients working with m0n0wall, 
I would love to know as well.

Thanks,
Michael
