Firewall::Cisco::Outbound PPTP

Can't do PPTP vpn for a client inside cisco firewall to a server outside. Using Pix 6.1x
Must allow GRE ("Generic Routing Encapsulation") protocol from the server in to the client.
This requires: - client must have static IP address.
- Outbound on TCP1723 must be allowed to the server
- Inbound GRE must be allowed from the server to the client's outside static address.
The details of this and other situations is found in Cisco document: "Permitting PPTP Connections Through the PIX"
