[Unbound-users] Lots of logging

Hi Mike,

The operating system tells unbound that it cannot send to a 'normal'
IP address.  (unbound has do-not-query and access-control in its
config to block IPs you do not like).

If you have a strange setup and traffic from clients not on localhost
arrives to 127.0.0.1 and unbound tries to answer back, then this error
is normal for trying to send to 192... with source address 127.0.0.1.

Otherwise, this must be traffic that unbound sends to nameservers
('upstream').  If you dig @192.203.230.10 , is that also operation not
permitted?

This error is not throttled by verbosity, because it is likely a local
misconfiguration.  The OS disallows network access to unbound ...

Best regards,
   Wouter
