Problem with IPv6 traffic since update 26.1.6

[odites999]

After trying many things due to the TLS handshake error I mentioned in another post, the only way I could get Opnsense working normally was by disabling IPv6.

I replicated the same configuration (VLANs, PPPoE, IPv6 over PPPoE) on another virtual machine on the same host but with OpenWrt, and everything works fine: IPv4 and IPv6 traffic, and test-ipv6.com (it recognizes my provider correctly and passes the test with a perfect score of 10/10). Therefore, I understand that something caused IPv6 to stop working with my configuration during the upgrade from version 26.1.5 to version 26.1.6. Is there a way to revert to a previous version by downgrading the version packages if necessary to try and pinpoint the problem?

Thanks in advance.

Ehh... is this what you need : https://docs.opnsense.org/manual/opnsense_tools.html ??
