IPV6 Prefix ID issue after upgrading to 23.05.1

@Gertjan said in IPV6 Prefix ID issue after upgrading to 23.05.1:
Just a wild guess : take your pfSense 2.7.0, note the MAC of its WAN.
Copy it over to the WAN of the pfSense plus.Or try rebooting the modem. Some require that with a different MAC.
Does IPv4 work properly? If so, that would rule out the MAC issue.

dhcp6-clienst (pfSense) asks for 3 /64 prefixes
How the heck do you manage that? You specify a prefix length, not the number of prefixes you want.

"Home made" dhcp6c config file.
See here.
( Google translate mandatory ^^ )I'm waiting for the new firmware to be released.

You specify the prefix length, which means only powers of 2. Last I checked, 3 wasn't a power of 2.

There have been a few slight oddities with v23.05.1 with IPv6 in certain configurations. Often a reboot is all it takes but there are a few config tweaks on IPv6 that can help, if needed.v23.09 dev seems (so far) slightly better with IPv6, which is reassuring.
As you didn't mention them, don't forget about the 2 pages under this tab, especially RAs and Router mode:

@RobbieTT Thanks for your feedback on de dev release. What worked for me (until release 23.05.1) was the following config:
- WAN VLAN 100 for getting a connection with my ISP
- System - Advanced - Networking: Allow IPV6 checked, Do not allow PD/Address release checked
- Interface - WAN: IPv6 Configuration type selected DHCP6, DHCP6 Prefix size 56, Request only an IPv6 prefix checked
- Interface - Opt2 with VLAN 10: IPv6 configuration type is track interface, IPv6 interface WAN selected and IPv6 prefix ID is 1
Here it already is getting odd, because on the dashboard under interface, I now see under WAN 2 IP addresses (my IPv4 and my local IPv6), but under Opt2 I only see my IPv4 and nothing regarding IPv6.
Then under Services - DHCPv6 Server & RA:
DHCP:
- DHCPv6 enabled for this interface
- using range ::AA - ::FFF
- prefix deligation size 64
- Provide DNS servers to DHCPv6 clients selected
RA:
- Router mode: managed
- Provide DNS configuration via radvd & Use same settings as DHCPv6 server are both selected
This worked, but suddenly ... no IPv6 addresses anymore with the latest release.

Yep, I had similar ripples but more intermittent. Switching to 'Assisted' mode helped enormously (and cured a small issue with Apple HomePods & HomeKit that, in itself, was triggered by an Apple update).
These settings worked for me (of course, use /56 rather than my /48):
Switching to Assisted mode (as recommended by a Netgate dev) was the 'magic' key for me.

@RobbieTT Updated my pfsense install to the latest DEV release, switched from Managed to Assisted...still no IPv6 on my interfaces :-(

Those have to do with DHCPv6 on the local LAN and have nothing to do with whether you get IPv6. I use unmanaged here.

Thanks for all your support guys, but nothing seems to work on my Qotom pfsense box with this release. Did a new install with CE2.7 and there it works fine. As soon as I upgrade to 23.05.1 the IPv6 network doesn't get any IP addresses. Therefor will put by Qotom box on the shelf for now and re-use my Dell R320-II for the time being. Looking forward for an improved pfsense release.
