In this video, we show you how to configure Proxmox to support VLANs on a single NIC We show you how to re-configure the management interface created during the installation so that it is in your management VLAN NOTE: Because we are switching to VLANs, the hypervisor will now no longer be accessible. However, connectivity will be restored in the next step so make sure you have the means to modify the network switch attached to the hypervisor Then we cover how to configure a network switch to support the VLAN tagging that Proxmox will now be doing Next, we show you how to add additional VLAN interfaces to Proxmox so it can access shared storage for instance And then how to configure virtual machines to support VLAN tagging Useful links: https://pve.proxmox.com/wiki/Network_Configuration#_vlan_802_1q ============================= SUPPORT THE CHANNEL Donate through Paypal: https://paypal.me/DavidMcKone Donate through Buy Me A Coffee: https://buymeacoffee.com/dmckone Become a monthly contributor on Patreon: https://www.patreon.com/dmckone Become a monthly contributor on YouTube: null ============================== ============================== MEDIA LINKS: Website - https://www.techtutorials.tv/ Twitter - https://twitter.com/dsmckone1 Facebook - https://facebook.com/dsmckone Linkedin - https://www.linkedin.com/in/dmckone Instagram - https://www.instagram.com/david.mckone ============================== Steps taken 1) Configure Proxmox The default installation creates a dedicated management interface so we need to reconfigure Proxmox with a management VLAN interface instead and make the Linux bridge VLAN aware The quickest way is to edit the /etc/network/interfaces For example, cp /etc/network/interfaces /etc/network/interfaces.bak nano /etc/network/interfaces auto lo iface lo inet loopback iface enp0s25 inet manual auto vmbr0.100 iface vmbr0.100 inet static address 192.168.100.10/24 gateway 192.168.100.254 auto vmbr0 iface vmbr0 inet manual bridge-ports enp0s25 bridge-stp off bridge-fd 0 bridge-vlan-aware yes bridge-vids 2-4092 Then we reboot Proxmox to make sure the changes are applied 2) Configure Switch Because Proxmox is now doing VLAN tagging but the network switch is not, we cannot access Proxmox remotely anymore so we need to reconfigure the switch port We need to turn the port into a trunk port i.e. one which supports multiple VLANs and set the default, PVID or native VLAN to something unused Once this is done, the switch will send VLAN tagged traffic to Proxmox and our connection will be restored 3) Add VLAN interfaces to Proxmox Proxmox will now have a VLAN aware bridge, which means we can add VLAN interfaces to it to give it direct access to a storage VLAN for instance To do this select the computer in the left hand pane, navigate to System | Network and from the Create drop down menu select Linux VLAN Change the name to match the bridge and VLAN ID, for example for VLAN 200, we'd use vmbr0.200 Give the interface an IP address and mask, for example, 192.168.200.10/24 Then click Create On the switch, update the port connected to Proxmox to allow this VLAN Proxmox should now have access to other computers on your network in this VLAN 4) Assign VMs to VLANs Because Proxmox and the switch are using VLAN tagging, virtual machines will need to support these as well For existing virtual machines, select the VM in the left hand pane then select Hardware Click on the Network Device then click Edit In the VLAN Tag field, enter the VLAN ID then click OK On the switch, update the port connected to Proxmox to allow this VLAN if that hasn't already been done You will need to repeat this for any other interfaces the VM has For new virtual machines, you can add the VLAN tag as part of the installation process when you get to the Network tab Credits: LoveLife | Instrumental Prod.
