Hi!
I was running opnsense 25 for a good while and everything worked fine, now i tried to update to the current version 26.1.11_10 and all seemed fine at first.
I still had to manually tell my WAN interface to reload so I could get a DHCP lease from my ISP but then I got an IPv4 address and an IPv6 address and routes/dns and I was finally happy (I tried upgrading from 25 to 26 twice in the past with the same result as now!).
i could ping IPv4 and IPv6 hosts and generally use IPv6 sites normally.
Then, a few hours later (maybe 2 or 3) i realize that my IPv6 is not working anymore!
But I still have an IP...forcefully renewing the WAN interface didn't help.
IPv4 traffic still works like a charm.
the last 2 times I tried this upgrade I ended up ditching 26.1 and reverted back to my older opnsense 25 because i couldn'T solve the problem.
I am annoyed by this because it is obviously something that changed from opnsense 25 to 26 since when i revert to a backup from before the upgrade it works again with no problem.
On a side note:
I get a static public IPv4 and a static /56 prefix from my ISP
EDIT:
my configuration:
opnsense VM running on TrueNAS scale with dual intel i-226 NIC directly passed through to the VM
previously working version: 25.7.11_9 (Commit 2e9ac2def)
I have WAN and LAN configured on the 2 NICs, WAN DHCP on v4 and v6 (DHCPv6)
LAN uses Track WAN Interface for v6
I use ISC-DHCP for lan addresses and unbound for dns resolving
Could someone PLEASE help me with that issue?
Best regards
