Does this archictecture could be possible ?

[BenjiHS]

Hello, I want to do an architecture like into the following picture. However I don't if it's possible, because I have a single physical NIC.

Proxmox Cluster must be in a seperate Network than home network and OPNSense will act as a Firewall and main gateway for all virtualize infrastructure.

I'm stuck by managing network bridge and network interface on OPNSense.

Any help would be appreciate!!

yeah, you can have such a setup - you can either pass through the physical interface to the opnsense vm, or give it a nic on a bridge that uses the physical interface. your other guests would then use a second bridge that is not connected to a physical interface, but also connected to the opnsense VM.

Thanks for your reply, so to access mgmt PvE, I should set an IP address on another bridge interface ?

that depends what you want to achieve.. you either route that traffic through opnsense, or (if you haven't passed through the only nic), use vlans to separate that in front of the opnsense VM. you will find lots of threads here in the forum about virtualized gateways like that, with different variants.
