Help for little bit complicated network topology

[Lalyu_Lalev]

Hello,
From long time I want to virtualize some of the services that I'm using at home and the moment finally come. Here is what I'm trying to do:

Inet <-> Managed Switch <-> Pfsense <-> Proxmox <-> VMs

more devices (laptops, PCs, few dummy APs, etc.)​

And as you may guess I have only ONE nic on my host machine. Could you please give me some guides how to do it?

I've already spend a lot of time googling about this, I've also find another thread where almost the same topology is discussed, but without the managed switch which is added one more layer of complexity.

Any suggestions are welcome!

Hi,

From point of view of security, it is a bad network design. If I read corect your ascii lan design, you want to put pfsense as a main firewall inside in a Proxmox VM. If somehow your pfsense is broken/offline, you do not have any firewall.
I have something like you on a friend house. The big difference is the managed switch who can also do a lot of things, like firewall, bridging, proxy and others nice things. I create on this switch some firewall zones (Wan, lan clients, proxmox host, proxmox guests, and so on)
