iCloud private relay was a blind spot. Working out how to let those proxy ranges in. (I blocked all the CDN's but this is more of a surgical carve-out for specific Apple designated ranges) Extracting those carve-outs now.
Edit: Applied carve-outs for Apple's iCloud private relay proxies. (I think)
If anyone is curious why I have to block CDN's, they permit abusive behavior, abuse of their workers (apps) and other layers of their networks. Maybe in a few decades they will get on it.
