Default vmbr1 not connecting to VMs

[neatrasm]

Hello,

This is a fresh Proxmox 9.1.4 installation on new hardware. Everything is default as possible.
After putting in over 10 hours trying this out, and exhausting Gemini, I need help.

Why are my VM’s networking not establishing a network connection?
Proxmox does not show the VM’s MAC address. brctl showmacs vmbr1

Placing the VM on vmbr0, regardless of which router is connected, allows the VM to connect to the router.

This is a temporary network layout. I need windows to access my cameras to change the IP.
The Camera Ips are 192.168.1.x by default.

My Management Router is properly configured.
My Camera Router is properly configured.
Vmbr1 gateway is null.

Thanks for any help.

Please carefully describe your network in a diagram and use [CODE] tags to format your post for readability. So far the information do not add up. E.g. Why would you have an OPNsense guest on a PFsense box. Please put in some effort and supply /etc/network/interfaces from your PVE-Host.

There are two networks. Internet and Management.

To change the CCTV IP I need 192.168.1.x, but I don't use that address space normally.

I simply swapped the wires to make things simple, so I can use windows to run the software to change the camera ip.

I don't use windows anymore after they kept switching the gui around.
Once the camera is changed to another IP then I was going to set the network to the Finalized configuration.
