- I could not download large installers due to a proxy anti virus tool which manipulated downloads causing files to become corrupted.
- I needed to visit a website to find a solution to a problem, but the local proxy server found the content offensive and disallowed me to visit the site.
- I have stayed in hotels in which I was not sure that my internet traffic was not being monitored. I was hesitant to access remote services which required credentials.
- At the airport, the public Wifi can sometimes not be trusted. Someone could run a local hotspot with the same name and become a man in the middle intercepting credentials of people connecting to it.
The method described in this blog allows you to access external resources with few limitations in a relatively secure way. It makes it easy to circumvent most content scanning/manipulation. Do mind that this method might be a violation of certain rules/regulations/policies. When in doubt, first confirm you're allowed to use it.
In short what you do is
- Run an SSH server on a different location on port 443
- On the same server which runs an SSH server, run your own HTTP/HTTPS proxy server (or use the SSH server itself as SOCKS proxy)
- Connect to the SSH server
- Map the proxy port to your local machine
- Use the configured port as proxy server in your browser configuration.
