Hi Brian
Thank you for the quick reply.
But I fear they don't explain the routing issue I see.
If my country coordinator did not choose to announce it's /16, it is
routed via UCSD.
At the moment, my Mikrotik connected to the HAMNET AP on the next hill,
is getting: 44.142.162.123 via DHCP.
So if I got that right, this IP should be reachable via UCSD for the
'internet' world:
traceroute to 44.142.162.123 (44.142.162.123), 64 hops max, 40 byte packets

Noe, it isn't. From my point of view, this would be OK, as the hamnet
links could be very slow packetradio links and you do not want to
expose them to the bad things on the internet which constantly scan the
whole ip range. :-)
But then, why not just announce the /16 which are reachable via
internet? It's not that a bad pollution of the routing table as routing
single /24s.
And also the other way round, why am I not able to reach the ampr.org
primary DNS, over hamnet?
How, as a hamnet 'user' do I know which hamnet destinations are
reachable via internet and which ones via internet? I would need to run
a routing protocol for that and establish peerings, from a dynamic
IP?!?, but this is something the 'normal' user would be unable to cope
with and in my point of view, not the task of the user.
Well, my goal was initially to connect my DMR hotspot via HamNet so it
would work independently of my internet connection, but if the DMR
Master's HAMNET IP Address I want to connect to is not reachable via
hamnet, that does not make much sense.
