Allowlist vs blocklist configuration

[muonzoo]

What a great project - looks like exactly what I need for my home network.
Quick question - is there a quick way to set things up so there is an allow list and the default disposition is deny?
I admit I missed this in my quick scan of the code and look at the docs. Managed to bring up a container very easily to play around but didn't see it, or it didn't click for me.

Thanks again and I look forward to going further with this project
