I am searching for a definitive, plain-english answer to two questions that have bothered me for a long time:
My opinion - after years of experience and more years of net discussions... This is slightly changed after the discussions last week...
a) Should 44-net be accessible to non-44 source addresses?
It should be possible - but only in a highly filtered and controlled special case.
As one example, I've been turning on MRTG traffic charts on the various home and radio subnets. That page could be something that would be of interest in the non-44 world and could be safely shared.
b) Should non-44-net destinations be accessible from 44-net source addresses?
It should be possible - more than the incoming case above but still carefully controlled. Recently I've come to appreciate more the corporate structure where outgoing access is somewhat controlled. Somethings I've seen on some systems are a bit scary.
If the answer to either of the above is "yes", then there is the potential for traffic which violates radio licensing laws to be carried by radio.
As long as you have 'users' there is potential for traffic violations. That's the small price we pay for doing cool things.
Personally I block all traffic with a non-44/8 source or destination, but I was never sure if that is the "correct" policy?.
There is probably no universal 'correct' policy. Everybody has to weigh all the consequences of their configuration.
