Ok so my bro has decided that he has to be downloading anything with bitlord 24/7. This is obviously slowing down the internet for me, and xbox live!. We are both connected to a belkin wireless G router (F5D7230ak4). I know how to block his internet access when I please, using the mac filter, but he is obviously gonna get suspicious that his internet just randomly stops working. So what I want to do is close the ports which his bitlord program uses. Here is some info: Bro's Laptop | | | | [belkin router]========== Desktop computer | | | | My laptop ====== Xbox360 That's what our set up is like, me and my bro on wireless and another computer directly to the router. I had a snoop on my bro's bitlord ad found the listening port to be 14969, and the upnp ON. On my router settings I have an client ip filters option. I have tried inputting these settings: ip: 192.168.2.2 port: 9250 type (TCP, UDP, OR BOTH): Both block time: Always Enable box: ticked Here's a screen shot: i applied these on the router and went for another snoop on his laptop and the downloads were still going. Is there anything I am doing wrong? Cheers for any help!
