In linux kernel since version 2.6.20 (release Date: 2007-02-04)
This module adds support for PPTP (Point to Point Tunnelling
Protocol, RFC2637) connection tracking and NAT.
If you are running PPTP sessions over a stateful firewall or NAT
box, you may want to enable this feature.
Please note that not all PPTP modes of operation are supported yet.
Specifically these limitations exist:
- Blindy assumes that control connections are always established
in PNS->PAC direction. This is a violation of RFC2637.
- Only supports a single call within each session
To compile it as a module, choose M here. If unsure, say N.
