SSH dynamic (SOCKS) proxy

If you do not need a full VPN, you can use a dynamic proxy via SSH to reach an internal computer from outside the Institute:

First step: create the tunnel

Second step: use the tunnel

Finally, configure in your web browser localhost:8888 as the Socks V5 proxy.

This example is for firefox 60.esr, English version. Other browsers and versions may look differently. Type, of course, 8888 wherever 7777 is used these pictures.
