IPv6 downstream router (FritzBox) requires OPNsense to behave like ISP

Why do you delegate ULA prefixes? You can't use ULAs for Internet access.

Simply configure KEA with GUAs based on the static prefix you get from your ISP.

Quote from: Monviech (Cedrik) on February 12, 2026, 01:44:27 PMOkay so the routing from OPNsense to Fritzbox should be okay now.

Are you having Router Advertisements set up on OPNsense, so that the Fritzbox gets a default gateway advertised on the link its connected on (igc0).

I have is activated without specific settings per (V)LAN interfacve; I added a specific configuration for LAN and disabled it, so for LAN it should now be disabled. I did not notice any difference in behaviour in any of the systems.

I would use GUAs as well, maybe the Fritzbox is weird here.

Anyway if the following is true its not a routing issue anymore:

-> KEA leased IA_NA and IA_PD to Fritzbox
-> KEA installed a route targeting the link local address of the Fritzbox
-> There are Router Advertisements sent to the Fritzbox
-> The IPv6 default route of the Fritzbox points to the OPNsense router

Though I probably cannot help more now if there's no bug to hunt anymore. Routing should be clean now.

(Also, setting the /48 GUA prefix in KEA does not mean it takes authority over it. You can safely do that, just be careful with the range you use for IA_PD so it doesnt overlap with what you use on the interfaces of the OPNsense and you are good.)

Dear Naurice and Cedrik, once again many thanks for your support and comments. It *seems* to work now with KEA with GUA + Legacy Track Interface + RA without configuration active for LAN. There were two things needed: 1) the route must be set up; this is now working fine after the patch and 2) I originally set the delegated length in KEA to a value lower than 64, knowing that Fritz needs at least 2 /64 prefixes. Then I read in some documentation that ISC DHCPv6 supplies prefixes in /64's; when I changed the delegated length in KEA to 64, also Fritz accepted the prefixes for both its guest and non-guest networks (the numbering is slightly different than in the ISC DHCPv6 case, but that doesn't matter.

It is running now for a few hours; maybe it is too early to give a definitive judgement, but I am alreay v ery happy about the result. Onve again, many thanks!

Thank you for providing info that helped to find a bug and verify the prefix delegation with KEA.

I feel like you were the first one trying (that I read), so the feedback was very valuable :)

Thank you. Maybe one suggestion: in the KEA documentation of OPNsense, the example for prefix delegation shows a delegated length of 56. It might be worthwhile to mention that there may be systems that require 64 as a delegation length.

I was a bit too early with my conclusion. Once transient effects (that need time, next to reboots) had passed, I saw that Fritz was getting a single /64 delegation, but not the second one for the guest network.

The Fritz documentations says: "A FRITZ!Box expects to obtain an IPv6 prefix of 62 or fewer bits (e.g., /56 or /60) from your internet service provider (ISP)."

In my PD Pools, I have both my Prefix length and my Delegated length < 62, so I imagine that I satisfy the Fritz requirement one way or the other.

In the leases files, however, I see consistently a Prefix length of /64.

Is the designed behavior?

Now my current KEA configuration (everything anonymized) is:

In DHCPv6 a client can request a certain prefix length from the DHCPv6 server.

If the documentation of the Fritzbox says it needs 62 or lower, I would first try to give it 62 by changing the configuration of KEA (delegated_len).

Maybe it cannot use 60 and then falls back requesting 64.

But that's all just assumptions, the KEA config looks correct.


------

Remove fritzbox from network, reconfigure the KEA PD pool to offer 62 prefix.

Stop KEA, delete the IPv6 lease database completely (or remove lines that are the old leases, your choice) so there are no remainders after changing the configuration:

/var/db/kea/kea-leases6.csv (and .1 .2 if there are)

Reboot OPNsense

Reconnect Fritzbox and see what happens.

-----

In the end the Fritzbox should get one delegated prefix /62, and it should use that internally to split it into multiple /64 prefixes.

Thank you Cedrik.

I did the following:
- Disconnected Frtiz
- stopped KEA DHCPv6 and deleted the csv's in /var/db/kea
- Rebooted OPNsense and power-cycled Fritz
- After OPNsense came back reconnected Fritz
- Fritz had connection buit no delegated prefix
- Started KEA DHCPv6 in OPNsense
- Saw Fritz obtained correct /60 prefix; saw no route message in KEA log also no error
- Fritz client could not reach internet via IPv6
- Restarted KEA DHCPv6 from the user interface (pressed circled arrow)
- Then I saw the route message appearing
- Everything works as expected now

Hello Gerhard,

this is what I expected.

Also that no route was installed initially. We guard the prefix watcher if no lease.csv files exist, so the watcher exited early. Restarting KEA started it after the lease file was there again.

Thanks for confirming, let's hope its stable now. :)
