What do you mean its blocking the *****? As in its slowing it down or actually blocking it? If its slowing it down, then you don't need to open the ports, for if they werent open it wouldnt work at all. You might need to add a Gamefuel to override a incorrect classification of the VOIP traffic. Application rules and gaming rules is if its working intermittently or not at all. But that could be caused by other things too. What do the logs say?
