So I finally got my pfSense firewall to work with my Comcast modem to figure out the prefix delegation correctly so that I could DHCPv6 on my LAN so that I could then set DHCP reservations so that all the machines would get the same IP address. Yeah.
Or so I thought. All my Mac machines work correctly; they lit up seconds after I set the pfSense in place. But the Ubuntu device needed a reboot. ipv6-test.com gives it a passing grade after the reboot and says IPv6 is working.
So the final step is to reinitialize MiaB one last time to that it can internalize the new (and hopefully final) IPv6. Well of course it won’t complete the install process. It won’t even let me specify the IPv6 address.
Primary Hostname: mail.server.pminj.org
Public IP Address: 22.214.171.124
Public IPv6 Address: 2603:3023:30e:a7f0::d:1077
Private IP Address: 10.10.10.2
Mail-in-a-Box Version: v0.43

I am assuming it is because it thinks it is on link-local?
eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

Trying to delete the link-local doesn’t work.
krettig@mail:~$ sudo ifconfig eno1 inet6 fe80::cb71:95e4:452d:3671/64 delete
getaddrinfo: fe80::cb71:95e4:452d:3671/64: -2

ifconfig: `–help’ gives usage information.
Anyone have any thoughts?
