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)?  Home | Main Index | Thread Index |
