I have searched the syncthing forums and it seems many people can use from this feature:
A per folder setting which only syncing when both computers are connected to the same wifi network.
I have multiple devices which might connect to multiple networks and have access to internet(Metered DSL) and I don’t want the syncthing to sync these folders over the internet.
This should be easy as I only want the sync to happen when the devices have the same IP range.
No I want it per folder,
I want one of my folders to be only synced when they are connected to the same WIFI network. (both WIFI have internet access which costs per GB) but I do not want the sync to happen when they are connected to different wifi.
