I have a PIX 515-R unit running 6.3(3) and just today after running fine for about2-3 months, the PIX stopped accepting PPTP connections on its outside interface. I reloaded the PIX, and now it is working fine. Has anyone else had this problem or have any ideas on how to prevent, or troubleshoot?
All other traffic was accepted fine. Only PPTP stopped working. This did happen once back about 2-3 months ago.
BTY, I setup my unit as being able to accept both IPSec and PPTP incoming call for remote corporate users. At the time when PPTP stoped working, Cisco VPN Client was still able to accept IPSec incoming call.
