hi,
Im doing Layer7 Protocols to block youtube and facebook on our router.
question: what specific part of the packet sent matches the Layer7 filter rule?
thanks!

This is explained in the summary of the L7 page on the wiki. http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/L7
Also, any attempts to layer-7-match either Youtube or Facebook traffic will be fruitless; they both use HTTPS. The router has to be able to see the traffic to match it.
