Configure public port forwarding from outside

[hungna]

Hi all,
I am configuring the network in my server in the form of IP NAT-accessed virtual machines. So is there a way to configure forwarding connections from outside to ports in virtual machines on the interface. Instead of configuring in the file /etc/network/interfaces. Because every time I change the configuration like that, I have to restart the virtual machine, which is very inconvenient.
In the image is my current configuration, and I want to configure it on proxmox's interface, instead of having to go here every time I need to change it. Each time change config, I have to restart the virtual machine.

I use proxmox version 7.3-3, I have configured FW on the UI interface, but I can't find that function on the interface, or maybe I'm not sure what function it belongs to. Can you guide me?
