VLAN aware or dedicated vlan network device(eth0.100)?


Jul 12, 2021
Here's my setup. pfSense is running as a VM of proxmox. `eth0` is associated `vmbr0`, and pfSense also has a virtual network device connected to `vmbr0`.

There are two options:
1. Make the network device `eth0` VLAN aware, and configure a separate VLAN device in side pfsense.
2. Create a virtual network device `eth0.100` and `vmbr0.100`, and pfsense just attaches to this bridge without know the fact that VLAN exist

May I get some suggestion on which one is better in terms of both performance and configurability? Thanks!
