Question about how to setup VM's with a dedicated ethernet port.

[Dnezar]

Is it possible to setup a PVE with several VM's using a dedicated ethernet port.
I'm using a workstation with a NIC on the motherboard, which I'd like to keep for configuration of the machine itself.
I have a 4 port Intel NIC card I want to use for asigning a dedicated LAN.
Or even better. I'd like to run OPNSense as a VM and give it the network card PCIe passthrough.
But I'm just new to virtual computing.
I've managed to setup a PVE with Secure Boot and Nvidia vGPU for dividing the GPU for 4 VM's.
It was a bit of a pain to set up, but I managed to get it right. I would like the PCIe 4 port NIC to split up as well similarly. Can't find much information about it online.

Just put the physical NIC as port into a new bridge (e.g. vmbr1) without giving it an IP address. Then you can use the bridge for the vNICs of the VMs.

One (involved) way is to use PCIe passthrough another (easier) way is to use a virtual bridge per Ethernet port (and dedicate that virtual bridge to a VM).

It's not uncommon to give Proxmox an IP on one (built-in) network port (without a bridge) and use a virtual bridge (connected to other ports) for the VMs, to separate management and VMs.

Or even better. I'd like to run OPNSense as a VM and 2make the network card

That's just a specific instance of the options above. There is also a whole sub-forum about networking with Proxmox, which might provide inspiration and experiences with this: https://forum.proxmox.com/forums/proxmox-ve-networking-and-firewall.17/

Thank you both. This will keep me reading a bit.
