I'm afraid this question was too basic for anyone caring to answer, but it's
somewhat queer to try out. Will such a datagram be passed up the stack?

Does it see them once (incoming) or twice (outgoing and incoming)?
If (as I presume) it sees them twice: will ``keep state'' work on them? I.e.,
if i ``pass out keep state'' and ``block in'' them, will they pass?
And what about unicast datagrams (from me to me)?
