don't know if there is a documentation gap or not, but it
seems that what is not so well understood by "the
community" is how the IS servers recognize IGates and what
is sent to them when no filter is specified by the IGate.
I think it is a lot better understood now - at least by
the readers of this list.</div>

I would caution against implying that IS Servers have any
"knowledge" or "recognition" of an IGate. What has been discussed
here is the behavior of the APRS-IS servers on every filtered port
regardless of what is connected to that port. Saying that the IS
server "knows" what an IGate is leads some people to believe that
the APRS-IS does some sort of active routing to select IGates for
message transmissions. There is no such capability built into the
APRS-IS. Every filtered port that has recently delivered a packet
for a given source will receive back packets of possible interest to
an IGate for that/those stations for some period of time. What the
connected program does with those packets is not a concern of the
APRS-IS network.<br>
