I have a 515 unit running 6.3.1 and just today after running fine for about
23 days, 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 by the PIX. Only PPTP stopped working. This did happen once back about 8 months ago, before we upgraded to 6.3.1, so maybe its one of my clients throwing bad data that locks PPTP up?
Without the log, its hard to say anything. Did you collect the syslog when problem occured. My suggestion would be to collect the syslog when the problem occurs. Also, did you see any taces on the console. If you do have the syslog, please share this to us and we should be able to comment on that. To the best of my knowledge there is no known issue on this.
