I believe GRE is supported.

I want to create a rule that would block anyone trying to connect to my PPTP server after being denied access once. I 
will be doing this using snortsam. 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?

Thanks!
