PFSense VM config, just can't quite get it

I have a proxmox cluster, I am trying to set up a PFSense VM, so that I can set up an isolated network of Windows VMs.

My address range of the cluster is I am trying to set up an address range for the Windows VM network of

I have set up PFSense with two interfaces. The wan, which is my proxmox vmbr0 and port eno1, and I have created a second bridge which is vmbr1 and port eno2, to be used as my lan interface.

Clearly, this is incorrect, as it's not just working, lol. The wan interface is actually catching a DHCP address, so I am assuming this is working as it should. Clearly, the lan is not. Any help would be greatly appreciated.
What network interface is your Proxmox host on? Is it sharing an interface with pfSense? Also, what and how are you planning on connecting to the windows VM? When I did this, I wasn't in a cluster, it was a single node machine. For my first attempt, the simplest solution was to have three NICs in the host: one for the Proxmox interface, and two for pfSense (WAN and LAN) as pass through devices. If you want separate IP ranges, are you going to use a managed switch and create VLANs or are you going to have completely separate physical networks? Originally I had the cable in from my modem, into the WAN port, a cable out from the pfSense VM to the switch, and then a cable back again to the management interface on Proxmox. I subsequently went to a separate firewall device and I now have only one cable from the switch to my proxmox host, but it is a tagged port, and I have several different IP ranges for my VMs all associated with different VLANs. A diagram explaining what you are trying to do might help. I have never figured out how to run pfsense as a VM with fewer than three NICs, but there is likely a way using VLANs. I am just not familiar with that trick.
