I am connecting a Windows PC and a Android Phone via USB teethering.
However, every so often the Network settings the phone selects will change (I can only guess it is a timeout or based on restart). And since that means there is now a “new” Network, my somewhat too agressive Firewall will get in the way.
While I can fix that, it is annoying I have to. Given you already had perfectly working network settings before.
Any chance you could save the previously used Network settings in the PC client, for the Phone to retreive? Make it a list, so multiple Phones have settings to use in paralell.
