This guide outlines the steps to set up a Linux bridge device connected to a physical Ethernet interface with a specific VLAN tag. In this article the VLAN tag will be assumed as 170 but it can be any valid VLAN tag/id. In the world of networking, a Linux bridge device is a powerful tool that acts as a virtual switch, connecting different network segments seamlessly. It operates at the data link layer (Layer 2) of the OSI model, forwarding traffic between connected interfaces based on their MAC addresses.

Installing Podman on Proxmox is rather straight forward. The initial idea for how to do this came from a post on the Serve the Home (STH) blog: Create the Ultimate Virtualization and Container Setup (KVM, LXC, Docker) with Management GUIs. In that article STH uses Docker and provides a Portainer GUI. In this example the Portainer GUI is going to be omitted and use Podman instead of Docker. The daemonless part of Podman is the real selling point.
