As Baker points out, UDP still runs over IP, which is a routing protocol.
 If you send packets over UDP, it usually needs to reach a specific

If you have no destination in mind, you may broadcast your packets instead,
for any receiving interface to receive. To do this, you'd need to set the
'broadcast' option. If you do that, you probably also want to set the
do_not_route option as well, to limit how far such messages would broadcast
(although, practically speaking, most routers will likely prevent your
broadcast packets anyway).
