A response on my last post pointed me in the right direction for the type of packet inspection I need (layer7). I found that the Routerboard OS has layer7 packet inspection built in, and all that is required is to add the appropriate signature and assign QOS rules to it. I can see the counters ticking away with other signatures (not ports) such as telnet, and dns, but the signatures I found for Quick Time and Flash are not working. Here is what I have? Anyone know what I need to change? Flash: [FC]WS[\x01-\x09]|FLV\x01\x05\x09 Quick Time: user-agent: quicktime \(qtver=[0-9].[0-9].[0-9];os=[\x09-\x0d -~]+\)\x0d\x0a Raymond
