I don't see any interfaces added to trusted, afaik firewalld requires an interface to be specified for a zone.

I can only advice you to look at the output of iptables and see if you can figure out why it doesn't work.

Thanks.  That explains it.  I thought they would be checked in a different order.  I solved this another way, by moving ntp to the public zone and deactivating internal by removing the sources. --- Chad Cordero Information Technology Consultant Enterprise & Cloud Services Information Technology Services California State University, San Bernardino 5500 University Pkwy San Bernardino, CA 92407-2393 Main Line: 909/537-7677 Direct Line: 909/537-7281 Fax: 909/537-7141 http://support.csusb.edu/ --- Disclaimer: This e-mail message is for the sole use of the intended recipient(s) and may contain confidential and privileged information protected from disclosure.

Right now firewalld is ordering zones by names and this also affects the sources bindings of zones. The internal zone is therefore handled before work and trusted. To make your setup working you can simply rename internal to Z_internal to make sure that it is handled last. I am sorry, but code to order sources (subnets) according to the size of the source has not been added to firewalld, yet.
