I'm new to snort and have a question that I can't find an answer to. I've got a box up and running. I'm now trying to suppress the "normal" traffic on my network. Two big ones that I see happening are: * PCs browsing on TCP/80 * Mail servers sending on TCP/25 In these two instances, snort is alerting 122:27 "(portscan) Open Port". If I suppress 122:27, I could very well also suppress stuff I don't want to (ie a trojan connecting to an IRC box on tcp/1337). Can I write suppression statements based not only on gen_id, sig_id, and src/dst ip, but also include tcp or udp port? Or am I approaching this the wrong way?
