Connecting machines without opening a port (preview)
2 min read
Your other computers - a laptop, a Mac, a second desktop - connect to the machine that runs your Gateway so they can share the same board. This preview lets them do that without opening or forwarding a network port on the connecting machine. It is an opt-in setting, turned off by default, and it is on track to become the standard way machines connect in a future release.
What changed
Before, letting another machine reach your Gateway could mean making that machine reachable on the network - opening or forwarding a port so the Gateway could contact it. With this preview, the direction flips: the other machine reaches out to your main machine instead of waiting to be contacted. Nothing on the connecting machine has to sit and listen for an incoming connection.
Why it is better
- Simpler to set up. There is no port to open and no router forwarding rule to configure on the machine you are connecting from. It reaches out on its own.
- Safer. A machine that never opens a port for an inbound connection has nothing extra exposed for someone else to find. The connection is started from the inside out.
Turning on the preview
Because it is a preview, the port-free connection is an opt-in setting you enable yourself - it will not switch on behind your back. Leave it off and nothing about your current setup changes. Turn it on to try connecting a machine with no port to open or forward, and expect this to become the default connection path in a later release.
