It tells you that you have connectivity to this other AMPR gateway. If those neighbor discovery packets ever stop, you know something has gone wrong and your tunnel to that gateway is broken. If all gateways ran this protocol, you could start collecting some health statistics for the entire network. Tom KD7LXL

Honestly, if you’re on the internet and expect to not get random packets, you’re deluding yourself. And any decent packet capture/analysis program is EASILY capable of filtering on anything your heart could desire. If you don’t want to see certain traffic, filter it from your capture results. On a personal opinion, 44-net and the tunnels are treated too much like a RF system. This is a network, similar to and attached to the internet, random stuff WILL come across, attacks will happen, and you’ll communicate like normal. It’s the responsibility of someone attaching an RF device to the internet to use firewalls or whatever other means to filter out the cruft as appropriate for their RF service. For example, if you’re in the US, and use Part 15, then perhaps you don’t care. If you’re on Part 97, then filter out what you don’t expect. Complaining on the mailing list about every stray packet one sees (and this is not the first) uses far more bandwidth than the 149 byte packet, and FAR FAR FAR more of everyone’s time. This is the internet, it’s an unexpected packet, that’s expected. Nigel
