Updated 9/21/2019 and firewalld is not working.

In looking at messages there are all kinds of firewalld errors.

I will keep searching.

Thanks for the help.  I did the following:

firewall-cmd –permanent –direct –add-rule ipv6 filter OUTPUT 0 -p udp –dport=5353 -j DROP firewall-cmd –permanent –direct –add-rule ipv4 filter OUTPUT 0 -p udp –dport=5353 -j DROP firewall-cmd –reload

Then I got:

Error: COMMAND_FAILED: argument of type ‘Rich_Destination’ is not iterable.

I am again stuck, could you advise if this is correct or incorrect what how to “removing the mdns rule from the firewall” is how I should have attempted it?

TIA.

Thanks very much.  I will 

I removed that rule from firewalld via the VitalPBX web interface.  I rebooted after the yum update and I still can’t get back into VitalPBX.  None of the rules are being added back in.  They are in the web interface but not being loaded into firewalld.  All that iptables -S shows is attached.

I used to remove firewalld and used iptables by themselves until VitalPBX came out with OpenVPN and decided to stick with ‘out-of-the’box vs. going back to just ipeables.  I haven’t really learned firewalld yet, I am not bad with just iptables.  I realize that firewalld is a different intrface that sets up iptables.  That is why I always went back to iptables and removed firewalld in the past.  This installation is only a couple months old with 100% VitalPBX.
