Comment 5 for bug 1842008

No, this is not possible for 2.7 as it's in RC. We're working on the some of the exposed/ports parts in the 20.04 cycle. We can try to make an extended look at this but given that controller machines are intended to be able to be ssh'd to if the user has access I'm not sure what the right fix is here.

If we have to solve an immediate customer need I might suggest we deploy a firewall onto the machines and get specific on what's required for that specific use case as we don't currently have a mechanism to model this correctly.
