[SOLVED] Proxmox VM "LAN" Between nodes

[flixhost]

Hello dear Community,

I was wondering how do I set up it the Best Way.
I have a simple 2 node test Lab.

The Problem:

I'm running on my first node a pf sense firewall which connects to WAN over vmbr0 and inject its "LAN" to vmbr100
So Basically every VM in vmbr100 is in the "LAN" Now I want to have this LAN on my other node pve2 to put a VM Also in the LAN to be able to communicate with the other VMs and out of pve1 to the WAN.

The Question I have is how do I accomplish that when I can only use that:

I have only Following Connections available:
WAN Switch has 2 Ports which are in multi cast and that's the up links ...
Then I have between pve1 <-> pve2 a copper cable.
That's it.

Kind regards and greetings from Frankfurt.

You need a physical interface in vmbr100. If you dont have other physical interface , you Can use a vlan tagged enp2s0.x if your network support vlan
