IPv6 PD not work after update OPNSense from 22.7.11->23.1_6

[dfw3xam1n3r]

I re-applied the patch, made sure it was applied, and so far, after two hours, it's still up. Hoping it sticks.

make sure to restart configd, it is required and was forgotten to be mentioned:

# service configd restart


Cheers,
Franco

[dfw3xam1n3r]

Thanks. So far so good. It's been running overnight with no drops.

My OPNSense WAN interface is not DHCPv6 but SLAAC.

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

Not sure this is entirely related, but yesterday morning zabbix reported ipv6 was down.  Didn't see anything obviously wrong aside from clients couldn't ping to the wan (didn't try local)...restarted radvd and it all came back.  It appeared opnsense still had a wan ipv6 address.  Using SLAAC.  Cheers.

Well I must have spoken too soon. IPv6 is down again today, even with the patch - and this time restarting radvd isn't getting it going again.

Do we have any new ideas to try? I hate having to reboot the whole firewall, it's disruptive and annoying to the other residents of my streaming-only TV house.

[dfw3xam1n3r]

I have found that after rebooting I have to re-apply the patch every time and then it works again.

[dfw3xam1n3r]

Adding more from additional testing. Not even using router advertisement or DHCP6 server anymore. Just static IPv6 addresses on internal server and OPNsense firewall. Still drops after 30-40 minutes. I apply patch, go to Interface, LAN, Save and it works again, until I reboot.

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

[dfw3xam1n3r]

I'll be upgrading later tonight.

[BrokenRouter]

I've been stable since the last time I posted so I'm leery of updating - I'll wait and see.

I haven't done anything to make it stabilize, I'm still in the same place - 23.1_6 + the aforementioned patch.

[dfw3xam1n3r]

Upgraded to 23.1.2, mine failed again, same issue. IPv6 route dropped upon DHCP6 renew.

[BrokenRouter]

I had an internet blip happen in the middle of the day and now I'm broken again.

I took the chance to go ahead and upgrade to 23.1.2 figuring it's not going to work less at this point - or if it does I can just disable IPv6 entirely until it gets fixed.

Anything further on your end cayenne or dfw3xan1n3r?

[dfw3xam1n3r]

For now, I have a static IPv6 address on LAN (no internal DHCPv6 or RA running) and DHCPv6 on WAN to pull IP and delegated prefix. Right now it's running and with no drops, but if I reboot it probably will do the same thing and drop after 30-40 minutes upon renewal. When I reboot again, we'll see.

[dfw3xam1n3r]

Had to restart it (due to unbound lack of ability to do dns lookups for some reason): same thing. Dropped ipv6 route after 45 minutes. Did a Save on the LAN interface, came back up for now.
