When connecting, I have 4 connections allowed. To the left appears either "Client" or Ultrapeer". When I have only 4 ultrapeers connected the system runs fine. Then other times I get a ton of connections called "Leafs"....These leaf connections are usually only 1 person each, I can never download when these leaf connections are around, and I mean I can't download ANYTHING. When I highlight all these connections and remove them, they pop right back up. And finally, when these leaf connections are up my firewall intercepts portscan attacks. How can I get rid of these leafs and just have an ultrapeer connection???
