I'm busy testing that but my IPv6 traffic doesn't cross the tunnel.
On Status / IPsec I'm seeing this, having defined two phase2 (one tunnel IPv4 
and one tunnel IPv6):

10.0.0.0/16     Local: cb9f5c9f         10.1.1.0/24     Rekey: 694 seconds 
(00:11:34)   AES_GCM_16      Bytes-In: 5,376 (5 KiB)
fd00::/64       Remote: cd70616c        fd01::/64       Life: 1495 seconds 
(00:24:55)                   Packets-In: 64
                                                        Install: 2106 seconds 
(00:35:06)IPComp: none    Bytes-Out: 13,768 (13 KiB)
                                                                                
                        Packets-Out: 105
As far as *I* can tell, it looks fine.
The remote and local subnets are fine (match my LAN subnets). Of course I have 
checked that I see the same thing reversed on the other end. On firewall rules, 
IPSEC interface, I currently have two pass-through rules, one for IPv4 and one 
for IPv6.

The other rules needed are supposedly added by pfSense (without displaying 
them) as System / Advanced / Firewall - Disabled auto-added VPN rules is NOT 
checked.

But are those auto-added suitable for passing both IPv4 and IPv6 inside the 
tunnel?

Phase1 is setup using IPv4 / IKEv2.
One Phase2 is tunnel IPv4 and the other is tunnel IPv6.

One end is 2.3-REL, the other one is 2.2.2-REL (which I cannot upgrade for the 
time being).

Would someone have an idea, based on their own experience with IPsec and both 
IPv4+IPv6, of what wrong in my setup to look for?

So much thanks for the help,
