I'm hoping to remove it so we don't have to worry about managing it. Today, it
exists for a reason (which I am still trying to understand). As I understand
today, it is used as a jump box to access some resource in
tripleo-test-cloud-rh1, assuming the controller and compute nodes. But is that
When things are working, there usually isn't problems. However, when problems
occur, it is another box that we have to loop into to trace outbound
connections. I think the most recent issues with DNS were a result of something

Yes, I think that would be the ideal setup. Removing any unmanaged linux systems
between tripleo-test-cloud-rh1 and the internet is the goal. This give tripleo
move control of the network and 1 less thing to depend on.

Pushing it off is one option, however I am offering up bandwidth to support this
effort. Last I have heard RDO Cloud is still 3-6 months away.
