It only opens up to another machine validated by public keys. It serves similar purpose as opening firewall to just a specific IP/port and dynamically change the IP/port as the other machine moves or disconnects. One of the main advantage is that it works behind NATs you don't control (i.e. public WiFi). Edit: also most home routers do not have the ability to dynamically open up to specific IPs based on where your outside machine is. |
