@feld on Charter/Spectrum@here if you don’t request the expected size via DHCPv6 it issues nothing. You’ll get the interface for the firewall by idk SLAAC or whatever it is but no PD, DNS, anything, if your PD request isn’t the right number of prefix bits (I think it’s /56? I’d have to look at my pfSense) … pfSense was also and may also so be broken, you can’t have more than one IPv6 upstream unless they’re static.
