"Why did it take 2 hours?"

I have a special configuration where I bypass AT&T's gear and AT&T's gear does some heavy lifting for you. They give customers a /60 so if your router/firewall requests an address without the correct configuratino it gets is a default gateway of ::1 which drove me fucking NUTS

Plus I found a few other small edge cases breaking radvd on my LAN but it's working now.

I don't understand this strange world.
