Hi, I want to configure firewalld (sorry no need additional software apache, nginx or squid, I need firewalld or config of my reversy proxy). I have running reverse proxy (polarproxy) in machine 192.168.0.106 (192.168.0.1/24). I want to redirect all inbound request to domain xxxxxx.com from this machine to machine 192.168.0.102 (where working local clone xxxxxx.com). Any other request to other domain need to going free to gateway of this network (192.168.0.1) and to inet.
What firewalld command I need? Or maybe config of polarproxy support this rules?

If you're using PolarProxy then you should look it up in their docs.

They describe an iptables redirect rule there, translating that configuration to nftables would be another question.
