Hello. I hope you are well.

I am new to Proxmox. I am having trouble getting Proxmox to recognize tagged VLANs.

I have used a server to install Proxmox VE 8.2. This server is directly connected to a switch. The interface is configured in trunking mode with the required VLANs. As an example, I will call them VLAN 10 (MGMT), VLAN 20 (Captive Portal Network), and VLAN 30 (WAN Network).

In the Proxmox network configuration, I have configured the Linux bridge (VMBR0) with VLAN-aware enabled. I also created 2 Linux VLANs: vmbr0.10 and vmbr0.20.

In the Linux bridge interface configuration, I set the bridge-vids option with the VLANs that I need Proxmox to recognize.

Proxmox does not recognize traffic through VLANs. VLAN 10 is part of the network where the management IP address is configured, but when the switch port is configured with tagged VLANs (switchport trunk allowed vlan 10,20,30), the Proxmox IP address does not respond.

Proxmox responds when I configure the management VLAN (10) as the native VLAN (untagged): switchport trunk native vlan 10.

I have applied multiple adjustments, including enabling the OVS Bridge, creating OVS IntPort with the VLANs I need, and associating them with the OVS Bridge, but it has not worked either.

I appreciate any help you can provide.
