Hmmmm i am now using a workaround: when i delete the old rules for vmnat.exe completely and creating them again by myself, it works.
It's funny because when i only delete the rules for vmnat.exe but not the entry itself and then i rewrite the rules, it doesn't work. So i have to recreate the whole entry.
That is definitely a bug, i dont know what it causes but it would be nice if someone from the support could try that out.
It is also strange because another VM, Linux Backtrack, works fine and i only have to set rules there one time.
So perhaps it has to do something with Win 7 Professional x64 in combination with vmware...
Beside this problem, i have another one: i dont know exactly when it started, but i could be after i updated comodo and shut down the system and started it again the next day.
The comodo symbol in the taskbar does not autostart, neither does the cfp.exe, altough the service and the autostart entry exist.
So i reinstalled comodo but that didnt help. In the moment i workaround that problem by creating a rule in the windows taskplan (i dont know if it is the right word in english? in german it is "aufgabenplanung") by that the cfp.exe gets started after loggin in to the windows account.
I know that it isnt so important to have the cfp.exe running because the firewall will work also without it.
But also sometimes when the cfp.exe was started and the system was running, it disappears from time to time.
I do not have any virus on my system ... as far as I and the AV softwares knows
Is there any solution? I googled but there were no solutions... only a handful of guys with the same problem.
