I recently had customer who had smart idea to protect Container Registry with firewall... Breaking pretty much everything in process. Now it kinda works after days of punching enough holes in... But I still have no idea where does something like Container registry pull stuff from, or App Service...
And does some of their suggested solutions actually work or not...
Convince them to add IPv6 and you’ll be set for life
They did!
But they network address translate (NAT) IPv6, entirely defeating the only purpose of this protocol.
It's just so, so painful that I have no words with which I can adequately express my disdain for this miserable excuse for "software engineering".
