By default SSH works behind port 22, and so one cannot establish a SSH connection through firewall directly. Let’s say that the firewall blocks all destination ports except port 80 and 443, which are used for HTTP and HTTPS connections. Keep in mind that this is different than the Psiphon android Application, that uses some fixed limited VPN servers(out of 100s of free servers) under heavy load.įirst lets see how to bypass firewall using ssh tunneling. Here’s a way to setup a proxy server inside the firewall which tunnels all the connection via Psiphon VPN. If you don’t have a private server outside the firewall, you can use a free open-source VPN Psiphon which is based on SSH tunneling instead of common OpenVPN VPNs.

If you have a private server outside the firewall, you can use SSH tunneling to redirect all your traffic via the private server(which acts as a simple VPN). Virtual Private Network(VPN) has become a necessity in today’s time, but most of the VPN services are paid once and quite slow in use. How to establish SSH behind a firewall, and use it to bypass port restrictions (Better than OpenVPN).
