A. Cisco IOS Software Releases 12.1T and later support PPTP pass through or PPTP over PAT feature. Refer to the “NAT – Support for PPTP in an Overload (Port Address Translation) Configuration” section in Cisco IOS Software 12.1T Early Deployment Release Series for more information. Refer to IP Tunneling – Configuring PPTP Through PAT to a Microsoft PPTP Server to configure PPTP over PAT or PPTP pass through on a Cisco IOS router. PIX versions 6.3 and later support PPTP pass through or PPTP over PAT using the PPTP fixup feature. This feature allows PPTP traffic to traverse the PIX when configured for PAT. The PIX performs stateful PPTP packet inspection in the process. Refer to the section on PPTP configuration in Configuring Application Inspection (Fixup) to configure PPTP fixup on the PIX. The fixup protocol pptp 1723 command configures PPTP fixup.
