I do work with a company that has multiple paths out, so I think I know where you're at. Solution was/is to have a single machine with multiple nics, have each path's get a spanned port, and then use daq to listen to all the each interface in each path. Bonus was that one instance of snort handles all external traffic, no matter which path it comes/goes. Hope that sorta helps.

Hello boss, I do understand your point of view but this won't help us at this point, i would like to know if there's a way i could set snort to match with only fragments of the packet, like only the GET or only the response.

Many thanks for your help.By sensor are you meaning a different machine/snort instance/interface? Could you describe it in a litter more detail?A sensor is basically a machine, and each machine has one bridge with one snort instance running. The two machines have the very same configuration. What happens is that in some situations we have the inbound packets trough one machine and the outbound packets trough the second machine, as mentioned early this way snort signature are not matching.James ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
