wow.. really??? that would seem to indicate that they are, in the first place, 
using the mysql TCP port of 3306 for their communications... if so, that doesn't 
seem nice at all...

those rules check for the non-existence of several flowbits... could that be 
part of the problem if you have the rules that set those flowbits disabled??

i do note that those rules do set flowbit sslv2.client_hello.request but that's 
not one of the ones being checked...
