A cron job might be in reach for me, coding GUI not... :-(

Thanks for the info anyways...

PS: Ok, I had a look in System -> Settings -> Cron, is this the "Renew DNS for Wireguard on stale connections" entry in the drop-down?

Does it really check for stale connections? Or should I simply run it every 3 min or so?

Many thanks in advance!

PPS: My local networking nerd evaluated that the underlying script of this cron job mentioned above checks for handshakes and if too long ago it restarts the wg instance. Hope I got it correct...

Correct. The script checks if the last handshake was longer than 135 seconds ago and if so, restarts the connection, resulting in a new DNS lookup if name-based endpoints are used.
