OpenMPTCProuter configuration on Proxmox

[Mark979]

I have a mini-pc/firewall on which I recently installed Proxmox and OpenMPTCProuter. I have the following configuration: Proxmox on IP 192.168.2.253/24, OpenMPTCProuter on IP 192.168.2.1 and 2 routers set up with static IP address (192.168.9.1 and 192.168.10.1). I loaded the WAN ports of my minipc/firewall into the virtual server (I have 4 on my device). The first question is: have I configured everything correctly? And now I would like to understand what values to set in OpenMPTCProuter in the interfaces screen (static IPV4 and Gateway IPV4) because I'm not very expert...I will also post the Proxmox configuration I have now.
Thanks in advance to everyone.
