M38a3 Posted February 25, 2016 Report Share Posted February 25, 2016 Hi, I setup 3proxy on a remote computer that I would like to use as a socks5 proxy. I set my settings on uTorrent and I can download, but I only get 1/4th of my connection speed and sometimes the trackers on torrents say “timed out”. So I decided to turn on logging on my 3proxy app to diagnose the problem. 3proxy logs show the IP and port that the application is trying to connect to as well as the DNS for that IP and the port. From what I can tell, utorrent is trying to connect to my local IP on my port set in utorrent, it’s also trying to connect to 127.0.0.1. I don’t understand why it would do that… does anyone know? The problem is not 3proxy, I have tried two other proxy programs on two other machines and the results are the same. 160121021645.952 00421 - 1.1.1.1:7698 0.0.0.0:0 0 0 0 UDPMAP 0.0.0.0:0 160121021647.028 00013 - 1.1.1.1:38898 127.0.0.1:13617 0 0 0 CONNECT 127.0.0.1:13617 160121021648.978 00421 - 1.1.1.1:2519 0.0.0.0:0 0 0 0 UDPMAP 0.0.0.0:0 160121021651.958 00421 - 1.1.1.1:62342 0.0.0.0:0 0 0 0 UDPMAP 0.0.0.0:0 160121021654.968 00421 - 1.1.1.1:35460 0.0.0.0:0 0 0 0 UDPMAP 0.0.0.0:0 160121021657.964 00421 - 1.1.1.1:13777 0.0.0.0:0 0 0 0 UDPMAP 0.0.0.0:0 160121021734.046 00013 - 1.1.1.1:27887 192.168.1.20:13617 0 0 0 CONNECT 192.168.1.20:13617 160121021736.964 00421 - 1.1.1.1:28996 0.0.0.0:0 0 0 0 UDPMAP 0.0.0.0:0 160121021739.974 00421 - 1.1.1.1:56012 0.0.0.0:0 0 0 0 UDPMAP 0.0.0.0:0 160121021742.018 00013 - 1.1.1.1:57438 192.168.1.20:13617 0 0 0 CONNECT 192.168.1.20:13617 160121023528.184 00000 - 1.1.1.1:26139 54.239.168.143:80 154 1891 0 CONNECT cdn.ap.bittorrent.com:80 160121031014.980 00094 - 1.1.1.1:9845 54.90.121.236:7052 5521 2135 0 CONNECT rapton-i-57fa85bc.utorrent.com:7052 (I have replaced my IP with 1.1.1.1 for this log) There are a lot of lines that say UDPMAP, I’m not sure what that is.

DreadWingKnight Posted February 25, 2016 Report Share Posted February 25, 2016 The problemis proxies in general. They block traffic methods used by uTorrent. Link to comment Share on other sites More sharing options...
M38a3 Posted February 25, 2016 Author Report Share Posted February 25, 2016 Can you be more specific? I thought it was as simple as TCP and UDP protocol, both of which are supported by the proxies I have tested on. I have verified using wireshark that the traffic on the proxy is being sent out through the proxy and also incoming UDP connections are being proxied as well Link to comment Share on other sites More sharing options...
DreadWingKnight Posted February 25, 2016 Report Share Posted February 25, 2016 Depending on the proxy provider and/or software, some of the more advanced functions needed aren't supported. UDPMAP is one of those functions that is used extensively when dealing with uTP support. Link to comment Share on other sites More sharing options...
