Proxmox Networking Explained: VLANs, Bridges, and vmbr0

Configure Proxmox networking — bridges, VLANs, and VM/container network interfaces using official Proxmox GUI screenshots.

Step 1: Management Network During Install

During Proxmox install, configure the management interface IP, gateway, and DNS.

Step 2: VM Network Configuration

When creating a VM, set bridge (vmbr0), model (VirtIO), and VLAN tag on the Network tab.

Step 3: LXC Container Network

Configure container network bridge and IP settings on the Create CT wizard.

VLAN Example (/etc/network/interfaces)

auto vmbr1
iface vmbr1 inet manual
    bridge-ports enp3s0.100
    bridge-stp off

Assign VLAN Tag on VM Network tab when using VLAN-aware bridges.
