my PPTP connection stopped working. In the log it shows this:

So it seems that GRE isn't working correctly. Maybe it is UTM9 related, becaus in 8.*** I never had this issue. Rebooting didn't solve the problem.
My UTM is connected directly to the Internet via PPOE so it is no second hand GRE problem, it is the build in in UTM
EDIT: More information: I use local authentification and the clinets I try to establish the connection is Win XP and Win7, it woked before and no settings were changed by both, the clients and the UTM PPTP remote access because of restoring V8 config file to UTM9.
Hope you can help me, thanks,
Albeck.
