I had the same problem. I also tried to connect from external IP
located behind firewall without any rules. I couldnt connect to pptp
server also [with timeout]. Then I recognized then unloading
ip_nat_pptp module causes the connection could be achieved correct.
[Other related modules ie. ip_conntrack_pptp, ip_conntrack_proto_gre
doesn't influence connection].

NB> I run Debian 3.0 (woody) Kernel 2.4.20 and iptables 1.2.7a with the patched

Also working on the same setup [+latest official path-o-matic].

Regards,
