Attempting PPTP behind PIX

[sdmarek]

i am sittng behind a Cisco PIX 506e and attempting to connect to a GTA GB-800 using the Microsoft Protocol PPTP

I tested the remote VPN by bypassing the PIX, and it works great, but when i am behind the PIX (on the network that is protected by the PIX) i can not get PPTP to go through the PIX

What do i need to do to get this to work? i am assusming that i need to do an Permit ACL, a PPTP pass through or something, but every attemt i tried has failed

if you got an idea, please let me know

here is the running configeration for the PIX, and suppos the IP for the device i need to PPTP into is "99.88.77.66" what would i do to allow anyone from my network, to passthrough the PIX, into the 99.88.77.66 device, using PPTP? i do not know if this is an ACL problem, or maybe a NAT/PAT problem or what, please help if you can
