I had to add some rules to a CentOS 8 server because some things stopped working that were previously working. (Not sure why this worked before, but it did)
Adding a few rich rules resolved the issue immediately.
None of this makes any sense. It's deny all and permit by exception. Why would you do anything else?
That's the default, and that's what was working just fine for a long time. Suddenly it began "not working" and needed the exceptions made.
