Hey Thanos,

You can only set one suppression per gid:sid pair so you can't at the moment fully exclude a gid:sid by suppression.

Are the alerts you are trying to suppress with 0:0 based on builtin rules?  You may be able configure multiple policies 
differently to work around some cases.

Also, I'm curious about your suppression of 119:225 and 119:228. Can you share any data on those like -A cmg output or 
maybe a pcap?

Thanks
Russ
