Proxmox VLAN Configuration: Linux Bridge Tagging, Management IP, and Virtual Machines

Proxmox VLAN configuration can be challenging if you haven't seen how this is done. However, we walk through this process step-by-step and show how to make Proxmox VLAN aware, move the management IP, and add VLANs to Proxmox virtual machines.

Thank you so much for this video!! I am new to Proxmox and this was the best tutorial for networking part! You are a great instructor!

[hibbertsa]

This video saved my life! 50+ hours in and you finally helped me. Thanks so much!

[vtransplant]

This video is spot-on and simple to understand. Thank you for taking the time to illustrate. 🙂

[dleemt]

Thank you SO much for this video. I was stuck on getting into the web gui on my newly deployed ProxMox server due to needing to have the management IP address on a specific vlan. this was an extremely clear and straightforward tutorial. well done.

[Kaffius]

Super helpful. fixed up my issues with my bond0 and truenas networking.

[matthewbennett]

worked a treat thanks for this video helped a lot.

[jwilk]

Thank you very much for this video. Very informative👍

[jegwebb]

This was sooo good! Thank you very much! :)

6:13 from manual - If you made manual changes directly to the /etc/network/interfaces file, you can apply them by running ifreload -a
This will avoid rebooting pve as I understand

[jstnumber]

You are a gentleman and a scholar. Thanks!

Wish I had seen this weeks or months ago; learned the hard way thru experimentation on some of this; learned other stuff however ; so not a loss. The experimentation was, uh, frustrating because not only had I added a new 4 port NIC, wasn't sure that it was working or not.

Was tired of replugging things to move them at a switch; Now back to work..

Thanks for the video.

[NADIRBAACH]

thanks for this video, i like your job, you have my light in this life, juste thanks

Personally I do this slightly different: create N bridges for all my VLANs and then bind each of them to port enp4s0.X. Then create N Linux VLANs enp4s0.X . I found this more readable to which VLAN my VM is connected to. Having said that - looking forward to see how we can use SDN introduced in recent version of Proxmox.

Just a note that may come in handy. For larger Xeon servers, such as xeon gold, we ran into a problem with VLANs being broken due to spectre and meltdown mitigation's. I had to disable them. While this may be fixed in Kernel 6.5, I had major production issues with 6.2.

I want to see an updated video for VLAN management using the new SDN features with existing externally managed (UniFi) VLANs including tagging the host os

[stevefxp]

If i make a vmbr vlan aware does that mean the corresponding switch port would be setup to tag only the vlans to be passed?

[Ecker]

Have you looked at how the new SDN interface in PVE 8.1 works?

[fasti]

If I make vmbr0 VLAN aware but don't set a VLAN tag in the network device net0 of a VM, will the latter act as a VLAN trunc so that i could use that VM as a docker host and putt the docker containers on different VLANs using 802.1q MAC VLANs in docker?

[truckerallikatuk]

What do you do if checking "Vlan aware" makes your NIC choke up? My Connect-x3 can only listen to 126 vlans at once. I only need 3 vlans.

[igordasunddas]

Does any of this change if I want to deploy OPNsense/pfsense and use VLANs in there, too?
