A test, and you need the console or SSH to execute it :
On the main menu, use option 8.
Then :
dig @127.0.0.1 google.com
This test executes a dns request on port 53, 127.0.0.1. Unbound should be listening on that port.
Another test :
sockstat -4 | grep 'unbound'
This shows you on which interfaces unbound is listening.
I see :
unbound unbound 83642 5 udp4 *:53 *:*
unbound unbound 83642 6 tcp4 *:53 *:*
which means : unbound listens on every (like "all") interfaces, for IPv4 and IPv6, on port '53' (of course), using TCP and UDP.
This means that this :
dig @192.168.1.1 google.com
should0 give an answer = the IPv4 of Google
Btw : I presume your LAN IPv4 is 192.168.1.1 - take yours if yours is different.
This :
dig @192.168.1.1 google.com AAAA
should give the IPv6 is you have a working IPv6 setup.
