3333 Care should be taken to ensure that link-local packets are not passed to
3340 Remember that you filter both packets going
3344 Most connections need packets going in both directions.
3359 TCP packets are dropped if they do not contain at least 20 bytes of
3360 TCP header, UDP packets are dropped if they do not contain a full 8

3474 When disabled, UDP packets use endpoint-dependent mapping (EDM) ("symmetric"
