You have enabled the Firewall on the VMs virtual NIC. Did you also configure it properly to allow access?

That is on by default I think, but turning it off makes no difference unfortunately, was hoping it would... Still not seeing any captured packets though. Something is quite weird. Even tried "promiscous" mode, leaving Port blank... That should show something, right?

Edit: Only when I select WAN as interface I get some capture... :/ I don't get this. If I remove port and protocol I get some activity, but none on the one for Proxmox VM..

Removing Port & protocol on vlan 30 on which I am trying to setup an ubuntu, this was all it captured;

19:25:03.205680 IP 192.168.1.3 > 224.0.0.1: igmp
19:26:03.820911 IP 192.168.1.3 > 224.0.0.1: igmp

I suspect the issue is in your PVE config

Agreed. With my limited knowledge of package capture and your help I think we can conclude that pfSense seems to do what it is supposed, right? It certainly looks as if PVE is not relaying anything to or from it's VMs...

I tried a laptop in a switch port for the same VLAN I set for the VM, and although it per definition is getting it untagged, the DHCP server responds as it should...

The switch port, which is connected to Proxmox is a trunk with tagged VLANs as I understood so far.
If so and you connect a device to it, you have to configure its NIC for VLAN.

Can you post your interface settings of pfSense, please?
Status > Interfaces

Which interface did you run the packet capture?

I got it working (!) while composing the answer to you! Thanks a lot!! It turned out to be a misconfiguration on the 2100-switch after all, I had not added the vlan to the port I am using... Having done that it now works as it is supposed to. This feels really great, and I am sorry for all the trouble, but very grateful for such a great forum and to all that has tried (and) helped!

Thanks !
