[aprssig] Blocking and filters

[Lynn W. Deffenbaugh (Mr)]

So that's another way of saying that you can't block messages addressed 
to your station no matter who they come from, right?  Just trying to 
provide a clear, unambiguous answer to the original question.

A filter (either negative or positive) is in -addition- to the standard packets that are passed to the client by the port.  Filter ports, by definition, pass all message packets addressed to the client, all message packets addressed to stations the client has "recently" gated to APRS-IS, associated posits (associated with the prior 2 categories of messages), and packets seen inserted directly to APRS-IS by stations "recently" gated to APRS-IS by the client (helps client not clutter RF with gated messages for other IGates).  You cannot "block" any of these packets.
