1. Above is the /etc/network/interfaces of my Proxmox 8.4.1 which is wired to a OpenWrt via a trunked ethernet cable
2. VLAN1 is untagged whlie VLAN2 is tagged
3. My LXCs and VMs (guests) are able to get IP address from VLAN1
4. However, when I set the VLAN Tag to 2 on my guests, they are unable to get an IP address from VLAN2
5. To test, I swapped Proxmox with a VLAN aware MacOS on the same OpenWrt port and managed to acquire a VLAN2 IP address
6. What am I missing??
