As you can see in this screenshot, it's very complex for me to manage and master rules on my firewall... Is there a way to simplify firewall rules in OpenWRT? I have some questions to ask in order to decide which approach will suit best for me.
1/ Can i flush all zones and work only with default tables / chains (no zones)?
2/ Will I loose all the benefits of the GUI in Luci because it's working with zones?
3/ Do I have to clear rules in /etc/config/firewall too and only use iptables?
4/ Can I use nftables for firewalling AND keep iptables executable because some programs/scripts only work with iptables?
Thank in advance for your help
