Hi guys,
I'm fresh in Proxmox, just install version 8.3.0 and created my VMs.
I have VM that contain firewall (lest call it of "gateway").
Now, I want to reroute all traffic from all the rest VMs to pass through the gateway (both ingress and egress).
So, when my VMs send packet, it routes to my gateway, then continue out from the Proxmox server (or drop, in case my security policy), same for packet that sent to my VM.
But, without the VM send it directly to my gateway (it invisible from VM perspective).

basically, that function as SFC or service insertion: my firewall is VM that I want to chain:
I imaging there need to be some logical router that do this magic:

Is it possible to do that in Proxmox?

Thanks!
 
Is there a reason why you cannot configure a gateway inside your VMs?
