[libvirt-users] Default firewall rules and forwarding to a guest

Hello, I am trying to understand how libvirt firewall rules are loaded as I have firewalld and iptables services are disabled. Where is the configuration files for firewall and NAT rules for libvirt? How can I load default firewall rules if I mess things up Also I have realized that followings is default ACCEPT all -- 0.0.0.0/0 192.168.122.0/24 ctstate RELATED,ESTABLISHED but If I am to forward a port for a real IP to internal guest machine I need ACCEPT all -- 0.0.0.0/0 192.168.122.0/24 state NEW,RELATED,ESTABLISHED (NEW state is required) and also of course a forwarding rule iptables -t nat -I PREROUTING -p tcp --dport 3389 -j DNAT --to-destination 192.168.122.16:3389 Is there a place I can make this rules static with LibVirt (not playing with firewalld and/or iptables service for Centos 7) Regards.
