Application: Tencent/QQ Protocol: UDP Ports: 6000,8000,6001,8001 Initial communication establishment packet size: 72 bytes (client side) & 56 bytes (server side)Client side pattern:^\x02\x01\x4a\xf5\x01\x01\x0b\x39\x10\x09\x57\x6f\x96\xff\xff\xff\xffServer-side patterns:^\x02\x01\x10\x08\x01\x02\x41\xb9\xb4\x74\x57\xee\x79\xd4\xa0\x8c\xa6\xc1\x7

I would like to block this application with just the client side pattern. The server side pattern is too long.I have not had time to test the patterns.Hope this helps as a starting point to test & fine-tune the pattern.Regards,Deepak Seshadri 3q again.
