    Proxmox VM combining tagged and untagged VLAN traffic (host behind Unifi switch)

    Hello all! After 3 days of digging, I decided to ask directly: My proxmox host is connected to a Unifi switch port with a native VLAN 1610, also allowing tagged VLAN traffic for IDs 3510, 1620, ... That means the proxmox host is automatically in the 1610 VLAN. Setting up single-NIC VMs has...
