It's a fundamental limitation in the PPTP protocol, in that it isn't
NAT friendly, not either of the above. The fix is to either not NAT
(all public IP's), or use a PPTP proxy of some sort on your firewall.
There are such things for FreeBSD, but m0n0wall doesn't use any at
this point. Maybe in 1.3, but definitely won't see one in 1.2.
