I don't believe it is an issue of firewall/log rules.  Unbound is simply not 
listening on those interfaces, as shown by a "sockstat -4l":

USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
[[...]]
unbound  unbound    1123  10 udp4   10.5.5.1:53           *:*
unbound  unbound    1123  11 tcp4   10.5.5.1:53           *:*
unbound  unbound    1123  12 udp4   10.0.0.7:53           *:*
unbound  unbound    1123  13 tcp4   10.0.0.7:53           *:*
unbound  unbound    1123  14 udp4   127.0.0.1:53          *:*
unbound  unbound    1123  16 tcp4   127.0.0.1:53          *:*
unbound  unbound    1123  19 tcp4   127.0.0.1:953         *:*
[[...]]

Those IP addresses correspond to the primary addresses of LAN, INTERNAL, and 
localhost.  Missing are entries listening on the IP aliases, 10.0.0.1 and 
10.0.0.14.

Also, even though I also have 10.0.0.14 and 10.0.0.1 checked in the DNS 
Resolver settings, they are not included in the active 
/var/unbound/unbound.conf file:

[[...]]
# Interface IP(s) to bind to
interface: 10.5.5.1
interface: 10.0.0.7
interface: 127.0.0.1
interface: ::1
[[...]]

Only the primary addresses of the network NICs are included.

If I add "interface:" lines myself to this file and stop and start unbound from 
the command line then unbound listens correctly on the IP aliases, too.  For 
some reason, they are not making it into the unbound.conf file from the GUI 
settings page for DNS Resolver.

Cheers,

Paul.
