Since the packet that contains the  "Access denied" message is sent back to the PPTP client using the GRE protocol, does that mean that I can't create a rule that will alert on that packet? My understanding is that GRE is not supported at this time. Would it be possible for me to create a general rule that would look at the entire packet and just try to be very specific when it comes to content matching in order to get a match?
