I have a VPS and until now have been using a socks5 server on it.
The problem is that recently my ISP (I live in Iran) has figured out some way to interrupt it and I'm receiving the "blocked page" for websites which are censored even through the proxy service. I know in some way that the problem isn't with the VPS, it's located in Germany and when used with other ISPs there's no problem.
What is causing the problem? Isn't the socks5 connection secure? What are the alternatives?
ssh -D 9999
to your vps and use the localhost:9999 as the socks-proxy? support.suso.com/supki/SSH_Tutorial_for_Linux#SOCKS5_proxying
