Building Your First Virtual Router Using PFSense/OPNSense and Proxmox

Hi Shahid, How should this be configured in Proxmox and in OPNSense if I have additional laptop (1 NIC) running OPNSense which I want to connect to port 2 of the managed switch?

And (in addition) when I want to use additional VLANs as part of the LAN interface, for example for IoT, Services VMs in Proxmox(a.o. TrueNAS, Jellyfin server) or Guest VLANs, how can this be achieved? And what is needed then on the configuration of Proxmox and OPNSense.

Thanks in advance for your reply.
