DNS resolver still restarts after every "rc.newwanip" no matter whether the interface is selected in the configuration of the DNS Resolver (in/out interface).

I selected only the LAN interface as DNS Resolver (in/out interface).

# Interface IP(s) to bind to
interface: 192.168.20.1

# Outgoing interfaces to be used
outgoing-interface: 192.168.20.1

After, rc.newwanip event on the WAN:

Jun 3 08:52:40     check_reload_status     399     rc.newwanip starting vtnet0 

Unbound rebooted.

Please check.

It seems the problem is back in 2.7.0 - even if nothing has changed running rc.newwanip is restarting unbound.
