ipv6 - No traffic from the opnsense itself

[FuN_KeY]

Hello,

Since a few versions (possibly 21.x) my opnsense cannot connect over ipv6 from the WAN interface. I am pretty sure that it stall the update process ("pkg update" is stuck on "Update OPNsense repository catalogue").

I do have ipv6 connectivity: ping6 from LAN works - every other machine on the network get ipv6 just fine.

Any idea about what is going on here?

In the meantime, checking "Request only an IPv6 prefix" seems to do the trick
