[Bug 1304613] Re: nodes can't get out to the internet beyond the maas server by default

[Jeff Lane]

As for your question about the region... I don't know... that's
operating at scale.  The question there is probably one of hierarchy...
for example, would you have multiple, linked region controllers, or more
like a few region controllers and several cluster controllers under
each?

And in that case, perhaps you'd want to be able to arbitrarily set this
assuming each region and cluster controller is a physical machine:

Region1 -- Dashboard -- cluster 1
                                                 |-- cluster 2
                                                 |-- cluster 3
                                                 |-- cluster 4
                                                              |---node 1
                                                              |---node 2
                                                              |---node X

So perhaps you would want to be able to, via the dashboard, or some
other means say, Cluster 1 shoud be segregated and never pass packets
out, but cluster 4 are all web-servers and associated servers and DO
need to be able to send and recieve from the internet and cluster 3
contains the things teh web servers need on the back end (SQL, etc) so
Cluster 3 should only talk to cluster 4 and NEVER talk to the internet.

Or I don't know, that's really a VERY ugly example.

My original point was just that, by default on my very simple use case
(and also as seen with the Orange Boxes), the deployed nodes can't talk
to the internet without some manual futzing behind the scenes, and
there's no simple way to fix that if you don't know iptables scripting
and what bits to flip.
