This will not work.  Yes, you can trap SOME of the WIDEn-N packets
but that won't stop 4-4, etc.  PLUS, in NC we are putting additional
LANs up to support gating of weather bullitens and objects so they
don't go outside of the area. (We have someone on the Western part of
Virginia or NC that is sending out bulletins to a very WIDE area.)
So we don't have room to trap all these bad n-N packets.  By doing
away with WIDEn-N, we have freed up our network from a lot of packets
that used to come in from all over.  John's assessment is accurate.

I disagree.  As you coordinate the SSn-N you coordinate the LNKn-N.
We ALREADY have THREE digipeaters up on the 95LNKn-N and that was
within a month.  Not a lot of work there...

I think the next best thing is to eliminate the WIDE and TRACE.

I disagree.  Even letting WIDE4-4 through would bring in many packets
from hundreds of miles around and then we are back at square one.
