SSH Tunnel

The easiest way to create a socks compliant ssh tunnel:

From the computer inside the network:

ssh -D [port number] -fN user@server

Then you can configure the application or service on the machine to access the remote server via the SSH tunnel and port configured.

e.g.

ssh -D 3333 -fN user@server.com

bfgminer -S opencl:auto --socks-proxy localhost:3333 --debug
