I'm running a Fedora 23 workstation using FirewallD by default,the machine has 2 NIC's one for internal and external traffic.
so id though I'd config the firewall to reflect this with the following commands
firewall-cmd --permanent --zone=internal --add-interface=enp5s0 firewall-cmd --permanent --zone=external --add-interface=enp3s0 firewall-cmd --permanent --zone=external --add-source=18.104.22.168/32 firewall-cmd --set-default-zone=internal firewall-cmd --reload
how every all traffic is now being dropped even on IP I've trusted.. my next step was to disable firewalld from running entirely with
systemctl stop/disable/mask just to make sure it doesn't start again on reboot.
but event with the firewall disabled external connection are still being dropped.
Any help on the matter would be much appreciated
