Re: Internet only stations
Yes, the checkboxes govern "normal" IGate functionality. To gate arbitrary packets from the APRS-IS to RF, follow the steps below:
1) Hit Control-G to enter a test filter. Something like "m/10
+t/p +d/TCPIP" would get you stations within 10 km of your current
location, must be posit packets and have TCPIP in their
"digipeater" path. Note the "+" qualifier is APRSIS32-specific
and joins that filter term with an AND instead of the default OR
for filter terms.
2) After monitoring the test filter trace log for a while to ensure that you're not getting TOO many packets...
3) Hit Control-I to adopt the filter and gate those packets to your RF port(s) as 3rd party packets.
Note that there is nothing in the filter spec to prevent gating filter-selected packets to RF for stations that were seen on RF. So if you have any RF stations beaconing to the APRS-IS directly, you'll end up 3rd party gating their APRS-IS packets back to RF.
Filtered gating from the APRS-IS to RF is not something to be taken lightly. It is fraught with peril and quite likely to flood the local RF channel, particularly if an unexpected, mis-behaving APRS-IS station starts matching your filter.
I really recommend individual station filtering through the buddy
(b/) filter rather than any range-based filter. That way you are
individually selecting the stations that you will be using.
Something like the following in place of the m/10 shown above.
And play with the filters (without the Control-I) for days,
weeks, or even months before the event so that you get an idea of
just what packets are being select. And even then, when the
actual event starts and additional stations come out of the
woodwork, you have to keep an eye on things so they don't run

PS. The Control-G/Control-I is purposely not persistent and must be re-configured after every APRSIS32 restart. It is designed for targetted use and not routine, ongoing, (and likely) unmonitored gating of APRS-IS packets to the local RF environment.
