PPTP stopped working on PIX 515

We have had PPTP working for several months on a PIX 515 pair up until last Wednesday. Since that time no one has been able to connect via PPTP. Cisco VPN 3.x clients are working OK. As far as I can see, no changes have been made to the PIX config in the last few months that would cause this. Our PPTP config is below:

ip local pool pptppool 10.0.253.1-10.0.253.254

sysopt connection permit-pptp

vpdn group 1 accept dialin pptp

vpdn group 1 ppp authentication pap

vpdn group 1 ppp authentication chap

vpdn group 1 ppp authentication mschap

vpdn group 1 ppp encryption mppe 40

vpdn group 1 client configuration address local pptppool

vpdn group 1 client configuration wins x.x.x.x y.y.y.y

vpdn group 1 pptp echo 60

vpdn group 1 client authentication local

vpdn username aaaa password ****

vpdn username DOMAIN1\aaaa password ****

vpdn enable outside

Try enabling debugs as described in :

http://www.cisco.com/warp/customer/110/pptppix.html

and see / compare where things are failing with your setup.

We did enable debugs but were unable to see anything when monitoring a telnet session. We finally did a failover to our secondary, re-booted the primary, then did a fail back to the primary; after this, PPTP worked fine on the primary. What would cause the PIX to stop passing PPTP? No changes were made to the config.

SSH, PPTP debugs only show up on serial console. Unsure why it did not work until you had to do a failover. If you can reproduce this, then contact TAC.
