As far as I’m aware, at the moment there is absolutely no control as to who can connect to the Moon.
Traditional packet filtering doesn’t really work in my case because moons are used exclusively for nodes behind dodgy NAT with dynamic IP. And because Moon lives outside the ZT network, flow rules doesn’t even apply.
Moons won’t be a thing in 2.0. Probably won’t change this.
Would you share some more light on this please 
Are you replacing Moons with something else? Will it give us control over who can relay traffic via this thing? Or are you just saying that Moons are not getting any love in this particular release, maybe later.
Thanks. This feature request is not relevant then.
