- a computer with Linux with access to the Internet through a transparent http proxy;
- a server where you can run an arbitrary program.
It is required that the computer has Internet via the server (if the server can be dispensed with, the better) and jabber, ssh and many other things that need specific ports and a permanent connection can be used.
What solutions exist for this case?
Next, in any program you register SOCKS proxy "127.0.0.1.15555".
SOCKS proxy, as a rule, support almost everything.
You do not need to run anything on remote_server.
on the server, put the server, on the local typewriter client, get a tunnel, but what next to do with it (natit directly on the server or route further) you decide. Good luck
