So you're trying to make sure you have the right holes punched in the ACL to allow a VPN tunnel through to terminate on a Windows server?  What you're permitting is PPTP, IKE and GRE.  Based on, you may also need Protocol 50 (ESP) and UDP 4500 (NAT-T) and UDP 1701 (L2TP).

Everything is work now, not sure what the issue was, maybe just needed a server restart.
