Here is my finding, yesterday I have reinstall on my appliance OPNSense 19.1.4, and upgraded it to 19.1.10, everything was working fine, I did a backup of my configuration. Today 24h later, it looks like that I lose my IPV6 connectivity again ( it was the reason I decided to go for a full fresh reinstallation yesterday).
I did a reboot of the appliance, but no changes, still no IPV6.
I said myself, that there was nothing risky to try to reload the backup configuration I did yesterday, and that's what I did, and after the reboot, everything was working perfectly again, IPV6 included.

What could be the reason for that ? Why a simple reboot did not fix the problem, but a reload of the configuration did fix it ?

My ISP is Orange France, and I configured OPNSense as shown in the tutorial from OPNSense manual.

Bonjour depuis quelques jour, je ne peux plus prendre d'adresse IPV6 sur mon module OPNSense, de plus le DHCPV6 ne se lance pas sur OPNSense, même en manuelle, la même configuration fonctionnait il y a 1 mois de cela.
J'ai eu une panne de courant, est ce que cela pourrait avoir une conséquence que sur l'IPV6 ?
J'ai besoin d'aide car je ne voit vraiment pas pourquoi cela ne fonctionne plus.

I did the upgrade this morning from 19.7.1, and since then, DHCPV6 refuse to lauch. Any thing has changed ?

Hi I have this port forwarding rule that was working under 19.1, and now it seems it doesn work anymore, since I can't contact my plex server from outside my local network.



Anything particular to open the Plex server port ?
