- randomize mac addresses with every uplnk connect
- automatic vpn handling during uplink switch (only classic/simple
  client-setups for wireguard or openvpn are supported)
- email notifications after successful uplink connections
- automatically disable uplinks after n minutes, e.g. for timed
  connections
