I activated "VLAN aware" in the network config of the Proxmox host, rebooted the server and added VLAN Tags to the VM (Netgate Installer).
VLAN 5 has a DHCP server and is the WAN network, VLAN 6 is the LAN network.
The Netgate Installer doesn't get an address assigned and even if I assign a static address it seems like there is not network traffic. I also tested this setup with a LXC and Ubuntu VM and got the same results.
