Far too often we end up behind a proxy that limits our network access in one or more ways. There are however clever ways that in most cases allow us to work around the nuisances the proxies impose, and I've written down my "guide" on how to do it here!
This is a procedure I've used myself many times and I've ended up explaining it to others several times as well so I felt it was about time I wrote it down.
I've tried to catch most quirks and be detailed and accurate, but please point out if you find any errors or mistakes in there. I hope to be able to perhaps add more specific config examples and command lines as well to make it even easier to follow.
