If I put my server IPs in that list, it does not work.

So the word "domains" to me seems incorrect. Are you saying that every users IP would need added to this list? Because you just quoted the documentation, which makes no sense.

If my domain is blah.com at 1.1.1.1 - how do I restrict only my domain using the server. Because when I put 1.1.1.1 it fails to connect for everyone.

Not sure who understands what happens in real world pen testing, but if I can connect freely to anything, I can DOS it with my team in half a second with a few million requests.

So please explain, like I am a idiot, how to secure jot server. Because, nothing I do works.

Thank you.
