Hello everybody. My question will perhaps seem trivial to answer, and I hope it will, but please take a few minutes to help me if you can. I am trying to connect to a remote host (named "endhost") I cannot access except going through a proxy, and that proxy prevents me to use the ports I need (UDP 5000 - 5200). I used to make a ssh SOCKS tunneling to an intermediate host (named "intermediate") using putty+proxifier to redirect everything my computer (named "client") sent to the "intermediate" host, which allowed me to bypass the proxy. I am now trying to do the same with zebedee because the game I want to connect through that proxy uses UDP ports 5000 to 5200 and ssh tunneling can't work on UDP Datagrams. I guess that if a TCP connection can reach the host "endhost", an UDP datagram will too. This is why I tried to create a TCP tunnel from "client" to "intermediate", in order to reach "endhost". What I tried is following : Client-side : zebedee.exe -o clientlog -U 1080:intermediate:1080 proxifier configured as following : don't process zebedee proxy : 127.0.0.1:1080 Intermediate-side : ./zebedee -U -s -o serverlog I then fired a navigator on the client, which was not able to grasp google, and here are he logs : server-side log is : zebedee(31841/86672): waiting for connection on port 11965 zebedee(31841/86672): accepted connection from 192.168.68.158 zebedee(31841/86672): waiting for connection on port 11965 zebedee(31841/83280): ERROR: failed connecting to port 1080 on 127.0.0.1: (Connection refused) zebedee(31841/83280): ERROR: initial protocol exchange failed client-side log is : zebedee(4936/3832): Listening on local port 1080 zebedee(4936/3832): Listening on local port 1080 zebedee(4936/3832): listening for client UDP data zebedee(4936/3832): accepted connection from 127.0.0.1 zebedee(4936/3936): ERROR: server refused request for redirection to lunix121.ensiie.fr:1080 I guess I'm doing something wrong, so if you can help me, please do so. I'm ready to answer any question that can help solve my problem. Thank you for reading.
