There are most likely some relays which use a different IP for outgoing
connections than what is listed in the consensus, due to multiple IPs or
provider multihoming. Your scheme does not seem to account for that, so those
connections may fail. In effect you will be leaving the Tor network
permanently semi-broken by running a relay while employing such filtering.

In any case I don't think there is any reasonable threat scenario against which
you must protect by not just allowing all connections from anywhere to
ORPort/DirPort of a Tor relay.
