Connection priorities can be configured. -Multiple connections cannot be established over relays. +When connected via a relay, only one connection is normally established. +However, with some lucky timing, e.g. when attempting to reconnect after losing +a connection, it is also possible to establish one relay connection in each +direction, if the two devices are listening on different relays. In such a case, +the GUI will show `1 + 1` connections.
