VLAN Support

The following note will be a VLAN Walkthrough using OPNsense & Proxmox.

OPNsense VLAN Configuration

  • OPNSENSE -> Interfaces -> Other Types -> VLAN

    • Chose Parent (physical) interface
    • Give new device name (vlan0.x) and VLAN tag x (e.g., vlan0.300, tag: 300)
    • Apply changes.

  • OPNSENSE -> Interfaces -> Assignments

    • Select created VLAN device as 'New Interface'
    • Give the new interface a description (e.g., 'Example', etc.)
    • Select the "+" sign on the right (add)
    • Save changes.

  • OPNSENSE -> Interfaces -> [Example]

    • Enable interface
    • Set IPv4 Configuration Type to: "Static IPv4"
    • Input desired IP address and network CIDR for that interface (e.g., "10.10.10.1/25")
    • Save changes.

Proxmox VLAN Configuration

  • PROXMOX -> Datacenter -> -> System -> Network

    • Create a Linux Bridge (vmbr)
    • Make it 'VLAN aware'
    • Bridge the physical port being used for the VLAN
    • Add a comment denoting what the bridge is for (e.g., "Example (Tag: 300)")
    • Create bridge.

  • PROXMOX -> Datacenter -> -> System -> Network

    • Create a Linux VLAN
    • Set the VLAN name as "." (e.g., "vmbr1.300")
    • Set the IPv4/CIDR to match the VLAN interface assignment (e.g., "10.10.10.0/25")
    • NO gateway.
    • Add a comment denoting what the VLAN is for (e.g., "Example")
    • Create VLAN

  • PROXMOX -> Datacenter -> -> System -> Network

    • Select "Apply Configuration" to save changes.

Creating LXC's and VM's

  • PROXMOX -> Create VM / Create CT
    • Configure as you would any other virtual machine / LXC
    • Select the created Linux Bridge (vmbr) as the networking bridge.
    • Specify the VLAN tag to use (which should helpfully be noted in the bridge comment).

# OPNsense VLAN Configuration
> OPNSENSE -> Interfaces -> Other Types -> VLAN

- Apply changes.

> OPNSENSE -> Interfaces -> Assignments
- Select created VLAN device as 'New Interface'
- Give the new interface a description (e.g., 'Example', etc.)

# Proxmox VLAN Configuration
> PROXMOX -> Datacenter -> "YourNodeName" -> System -> Network
- Create a Linux Bridge (vmbr)
- Make it 'VLAN aware'
- Bridge the physical port being used for the VLAN
- Add a comment denoting what the bridge is for (e.g., "Example (Tag: 300)")
- Create bridge.

> PROXMOX -> Datacenter -> "YourNodeName" -> System -> Network
- Create a Linux VLAN
- Set the VLAN name as "<linux_bridge>.<vlan_tag>" (e.g., "vmbr1.300")
- Set the IPv4/CIDR to match the VLAN interface assignment (e.g., "10.10.10.0/25")
- NO gateway.
- Add a comment denoting what the VLAN is for (e.g., "Example")
