Multiple computers traffic problem (QoS)

I was wondering if anyone could explain which ports to forward, so that I may give Pocket Legends top priority? My kid's stream videos and download all the time and I lag out very often or my ping is in the 1000. Thanks a lot

Is this what you are looking for? http://www.spacetimestudios.com/show...l=1#post132858

I believe so but I'm not really sure how to set it up

Would it be possible to post a picture of my router setup screen and maybe help me fill in the details? I know it's asking a lot I'm just not computer savvy.

I don't have the expertise for that, but someone else might ;)

Thank you for replying to my question :)
