@Gromhelm That's interesting!

Exactly the other way round for my place:

Finally test-ipv6.com reports that I have ipv6 connectivity with 23.1.8 ... :o
Br br

Like me, who created this post.

Hi @franco,

Has the problem been solved?

I've upgraded to OPNsense 23.1.8 and I'm not having the same problem. The IPv6 default route is not deleted.

Hello,
I have just upgraded to version 23.1.2 and the problem is still there

My OPNSense WAN interface is not DHCPv6 but SLAAC.

Maybe the patch is just for those who are in DHCPv6 @franco ?

Can you try this patch?

Hello,

I have just tested the patch:
# opnsense-patch 9eaff5c21907d

it's not good.

As soon as Opnsense receives a router advertisement packet, the default gateway disappears in IPv6

Hello,
I have just updated OPNSense to version 23.1.1

The bug is not solved.
@franco

I have just tried to analyse what is happening with a network analyser.

As soon as OPNSense receives an ICMPv6 type 134 (RA: Router Advertisement) from the Freebox, OPNSense removes the IPv6 default route

The IPv6 default route comes back when I disable/reactivate the IPv6 gateway in web interface system_gateways.php.

Hello,

I have the same problem losing the default route but only in IPv6.
In IPv4, the WAN interface is configured as static IP.

Hi,


I have the same problem but only on the IPv6 gateway : https://forum.opnsense.org/index.php?topic=32263.0

same problem since a few months, forced to launch the reboot in console

Let's try this patch to diagnose... https://github.com/opnsense/core/commit/930685e7d6

# opnsense-patch 930685e7d6

Does it keep working after reboot?


Cheers,
Franco

Hello,

I just tested and it's not good.
I just tested commenting out lines 65 and 69 in the "/usr/local/opnsense/scripts/interfaces/rtsold_resolvconf.sh" file.
I then restarted the OPNSense.

It doesn't change the behaviour. The default IPv6 route would disappear after 5 minutes~ (it's random time).

The IPv6 default route has disappeared as of 17:02:22.

After restarting OPNSense, IPv6 was good for less than 5 minutes~ and I could browse the internet in IPv6.
after 5 minutes~, the IPv6 default route disappeared from "System: Routes: Status"
