Add OMV 7 to VLAN

johnvick Without seeing your Promox network config, I can only make a generic comment. Unless you're using pci passthrough on a host NIC ( your're probably not), your OMV virtual machine can only connect to a bridge device within Proxmox, e.g. vmbr0, etc. That bridge can be set vlan aware or not. If the bridge device you connect OMV to only carries untagged vlan 2, then it doesn't need to be vlan aware. However the virtual nic appears in OMV, using dhcp will show you if it's connecting to the vlan 2 or not. If the bridge carries multiple vlans and is vlan aware, then you need to use tag 2 on the connection between the bridge and the OMV VM. Again, in OMV just configure the nic with a vlan2 ip.

Here's an example:

In Proxmox

Interface enp8so is connected to the trunk port of a switch, which carries vlan 20,30,40, and 50.

VMs will connect to bridge vmbr1 which is vlan aware.

OMV VM is given a virtual NIC connecting vmbr1 tagged 20.

In OMV just use DHCP as a test on virtual NIC:

Quote from johnvick

Just bought a managed switch and have created VLAN with ID=2. From the Proxmox interface I have added two LXC containers and one OMV VM to the VLAN. In Windows 11 I have added a NIC to the VLAN. Tagging done on managed switch. All devices connecting. Problem is I can't add my main OMV device to the VLAN. What do I have to change in above pic (or elsewhere) to get it working? I want the IP for the VLAN to be 192.168.2.3. Any help appreciated.

I read this to mean "one OMV VM" and "my main OMV" to be the same thing. Guess I was wrong.
