Hi together,

I’d like to run the syncthing linux service (my machine is running systemd) only when a specific wifi (or list of wifis) is connected. Has someone done this before?

My motivation is to increase security (reduce attack surface) by not running a service with open ports on untrusted networks.

What I found so far:

1. I want the same behavior as on Android (_Settings_ → _Run Conditions_ → _Run on specified Wi-Fi networks_), but on Linux.
2. On linux, the [config option `allowedNetworks`](https://docs.syncthing.net/v2.1.0/advanced/device-allowednetworks.html) is nice to limit traffic to local networks only. However, it does not allow me to limit to a specific network.
3. Another user has a similar problem: [pause on metered wifi on linux](https://forum.syncthing.net/t/pause-on-metered-wifi-on-linux/26997)

Some more information:

- My system is using systemd and NetworkManager
- syncthing is running as user context, not system context

There is no such functionality inside Syncthing itself. How about using a firewall to block Internet access for the Syncthing binary?
