ISA 2000 through Cisco ASA 5540 - 13.Sep.2006 9:10:59 PM

We recently moved our ISA server from a Cisco router running IOS firewall to an ASA.  When we made the change, anyone with the ISA server's IP address as their default gateway are unable to use PPTP VPN from within our network out to the internet.  Moving the gateway of our ISA server back to the router running IOS firewall immediately remedies the problem.  Users that have direct access through the ASA to the internet via the NAT pool or static NAT Addresses are able to PPTP VPN just fine.  Has anyone seen this.  I am assuming that the traffic must be blocked but I have access rules allowing 1723 and gre.  This ISA at one time was pointed to our PIX firewall and PPTP VPN worked there.  Thanks in advance for any help.

you probably need to add the following command on your ASA..

fixup protocol pptp 1723
