Recursion not available

ebcdic

(Running 23.01 on an SG-1100)

I am running a DNS resolver on the router; clients get both its IPv4 and IPv6 addresses as DNS servers. If I look up a name with nslookup, I get this:

$ nslookup google.com
;; Got recursion not available from <IPv6 address>, trying next server
Server: <IPv4 address>
Address: <IPv4 address>#53

Non-authoritative answer:
Name: google.com
Address: 142.250.187.238

Is this expected? I've restarted the DNS server with no change.

Are your IPv6 addresses dynamic or static?

If you look in /var/unbound/access_lists.conf does it list your IPv6 networks?

If it's what I think it is, it might be https://redmine.pfsense.org/issues/13851.

You can install the System Patches package and then create an entry for 46b159032fef8c78783aa1a749d2238cfed7ac0d to apply the fix.

Bingo! Lookups now succeed over IPv6.

A minor point - presumably it's also a bug in something that the error from nslookup is "recursion not available" rather than "connection refused".
