SSH Tunneling

Backgrounds

Now as you have set up vpn, you still cannot access to all servers at home via normal ssh or normal rdp or normal vnc.

You need to connect to the vpn server first, then access other servers at home.

  1. Turn on your VPN.
  2. Create a new session, VNC protocol. Set up Basic settings normally.
