How to Make PPTP Connections Work Through a Cisco ASA

The most common reason  I find that PPTP connections do not work is because the inspect for PPTP it not enabled.

This is how you enable the inspect in the default inspection class:


conf t

policy-map global_policy
 class inspection_default
  inspect pptp
end
wr mem


This is needed whenever PAT is being used.
