title: How can I use socat to update the server in a restricted zone?
body: <p>How can I use socat or other software to download e.g. an update server in a restricted zone with my PC in the office which has access to the server via ssh and internet - full access?
  I made a sketch of what's going on.</p>
  <p><a href="https://i.stack.imgur.com/R8XBR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/R8XBR.png" alt="network" /></a></p>
  <p>PC / Laptop has full server access.
  There are no open ports from the server to the PC / Laptop.
  I will be grateful for your help.</p>
