Hey, I have a proxmox node running with 2 NICs. where one is for the interface management and the other card is for VMs and Containers to make use of.

My VLAN Settings look like this :

And the PVID Settings are :

IK, I’m doing some noob mistake. I have added VLAN Tags and made the network interface Aware too in proxmox :

Sample Configuration of container with VLAN tag :

Isolation between the VLANS works but they can’t access internet that’s the only problem I face.

    VLANs work on layer-2. A switch can isolate frames between VLANs and that’s it.

    You need subnets and a firewall if you want them to communicate with each other (layer-3).
