Alright, google is no help. The internet is littered with instructions on how to set up Squid as a proxy in a local network. While I can appreciate that for some reason that is completely beyond me, some people want to have a proxy server running at their home 24/7 that only THEY can access (except of course companies so they can filter out all the cocks and tits); I want to set up a squid proxy on a server I have in the US, so I can use it as a proxy server to watch some youtube videos that are geoblocked in germany (like so many nowadays)

If anyone can help me an/or paste me a minimal/simple config file to do something like that, I would appreciate it.

I have a simpler solution without any hassle: Buy a BlackVPN account and be happy.

And why should I pay even more money for yet another server when I already have one that is perfectly adequate?

is it a root server? first thing I'd try would be (as root):

apt-get install squid

I guess the rest then is done with configuration files, which should be explained in the manpages (or the internet).

No shit Sherlock

yeah and if you want to open and edit the config files, try
vi -m ~/.isuchA/smarta**

o.o

Ich weiß du hast google schon bemüht, aber hilft das hier eventuell weiter?

Eventuell reicht für diese art von forwarding ja auch was kleineres wie Tinyproxy
