Title: VLANs on multiple NIC ports on firewall
Post by: jphilebiz on February 18, 2025, 09:06:06 PM
Hi everybody,

I'm reconfiguring my home network and would like to (if it makes sense) to use vlans on multiple NICs on the firewall. Let me explain:
So can I make a VLAN work on multiple ports on the firewall? On all? If yes I think I need to create a bridge to do this correct? Am I allowed to configure two bridges (or more)? Same with the IoT network. Would I need to configure a bridge for vlans and one for IoT?

If my approach does not make sense please do tell me :)

Thanks!

You can create a bridge that has VLAN devices (subinterfaces) as members.

What you can NOT do is have a base NIC (i.e. untagged) be a member of a bridge and also have VLAN subinterfaces on that NIC at the same time.
