The `via` isn't relavent, since that only functions to determine which
device to send it out of. All the ordinary routing table will do is
direct it toward wg0. Once it hits wg0, then the allowed-ips entries
are consulted to see where to send it (the "cryptokey routing table").
See sections 2 and 3 of [1].
