LEAP 15 - Own Firewall rules script | allow hole lan to lan

Hello,

I want to know, where and how can I set my own firewall rules via script with iptables/ip6tables with LEAP 15?
Or, how can I allow all from lan to lan from the frontend in yast2?

Thanks,
Andreas

installing microfw from this repo, then use /etc/sysconfig/network/iptables and ip6tables files to set your custom iptables rules

Is a good choice for me.

Assign the interface you’re using to connect between LANs to the trusted zone.

Of course, this assumes that you already have an interface you can dedicate to the connection, if necessary a VPN.
