SSH Tunnel : Proxy or VPN

SSH let you create a PROXY to encapsulate some traffic and even creating a rudimentary VPN.

SOCKS Proxy

To appear with the remote server's IP, dig an SSH tunnel :

From your computer :

ssh -D 9999 -NT batman@athome.tld

Then, configure applications to use a SOCKS proxy on localhost port 9999.

With Firefox, it is configured in "Network parameters".

SSH VPN
