+If this option is enabled then tinc will search for UPnP-IGD devices on the local network.
+It will then create and maintain port mappings for tinc's listening TCP and UDP ports.
+If set to "udponly", tinc will only create a mapping for its UDP (data) port, not for its TCP (metaconnection) port.
+Note that tinc must have been built with miniupnpc support for this feature to be available.
