I am trying to setup a 2nd private DNS server in my private
network, behind the firewall (with DNS access enabled) and
I am able to resolve all of my local systems. However, I have
some problems. One involves SELinux and the other involved
forwarding as shown below:
1) SELinux errors are reported only when starting/stopping/restarting
named.
