pfsense with 4 public IPs - how to?

Hi there,

My ISP changed my router two days ago and gave me four public WAN IPs (x.x.169.149-x.x.169.152). So I want to run multiple proxmox hosts where the VMs use these 4 WAN IPs. I've installed pfsense on one proxmox host, which works on the main WAN IP (x.x.169.149). But I need to understand the network topology to make this work.

Should my ISP router become a passthrough modem which than routes everything to a VM which runs pfsense? Should each PVE host run pfsense as well? For example, my proxmox hosts have one nic installed.

I want to achieve that my home network can operate normally, TV setop boxes work, including port forwarding for some applications.

But I'd also have four PVE hosts, which run each 8-10 VMs; each host should use a separate WAN_IP while each VM should get a static ip. The same Portforwarding and UPNP settings should be used on each host. Ideally, I'd like to access each VM from the network. I thought that something like here could work - Multiple Public IP addresses In Use Single IP Subnet.

What is the best approach here to configure pfsense? I have read many posts and watched youtube videos but I am puzzled. Any help is really appreciated.
