Unbound no longer seems to be registering the opnsense routers interface addresses other than LAN interface.
from the console:
root@OPNsense:~ # dig opnsense.redacted.com a
; <<>> DiG 9.20.11 <<>> opnsense.redacted.com a
;; global options: +cmd

now reverse lookup of the LAN interface looks as expected:
root@OPNsense:~ # dig -x 10.23.10.1
; <<>> DiG 9.20.11 <<>> -x 10.23.10.1

But when I do reverse lookup on any other interface it doesnt return the name of the router:
root@OPNsense:~ # dig -x 10.23.20.1
; <<>> DiG 9.20.11 <<>> -x 10.23.20.1

It acts the same way with ipv6.
This is recent, maybe after last upgrade?
I have switched over to dnsmasq as dhcp server, but I have not forwarded anything to dnsmasq as dns.
