Greetings All,

I am having a sticky DNS issue with my home system.  I have a CentOS 7 box that does split domain DNS for inside and outside off my home network.  My gateway is a ( crappy ) ATT ADSL modem, but all of the other port forwarding seems to be working just fine.

I am using the same slave DNS hosts that I have always used, but they can no longer connect to my DNS port.

I have my firewall set to use internal as my default zone.  DNS is configured on the internal, external, public, and home zones, but still no luck.

I have a few questions.

1. Can I create a new zone, add the IP addresses of all off my DNS slave servers to it, and allow DNS through that way?

2. If I have just one network assigned to my default zone, say 192.168.10.0/24 does that mean all other networks are coming through the external zone?

3. Can I create a default zone for all traffic that is not otherwise specified?  Like a default route.  I can see adding 0.0.0.0/0 to the external zone, but there is no documentation that indicates that this will work.

4. Are there any good web sites that has more that the basic how-to use firewalld info?  All I can find a basic tutorials!

I’ll stop there as I have probably overloaded this email anyway.


 Thanks,
    James "Zeke" Dehnert
