Chateau LTE6 One SSID Vlanning

Hi everyone,

I’m trying to set up multiple VLANs on a single SSID using my MikroTik Chateau LTE6, and could really use some guidance. This is my first time working with this device and with VLANs in general, so I may have some misunderstandings.

So far, I’ve:

Created three VLAN interfaces (personal, IoT, and guest), each with its own subnet and DHCP server.
Set up a RADIUS server to assign VLANs and pre-shared keys based on client groups.
Configured the bridge VLAN filtering and tested the setup.
Clients are getting IP addresses in the correct VLAN ranges, which is a good sign. However, when I run packet captures, I’m seeing VLAN-tagged ARP traffic that I wasn’t expecting. I suspect the issue might be with how I’ve set up the bridge or VLAN interfaces, but I haven’t been able to nail down exactly what’s wrong.

Could someone point me to the minimal configuration changes needed from a default setup to get this working correctly? Specifically:

Do I need to modify the default bridge?
What are the essential settings for VLAN filtering, interfaces, and bridge ports?
Any help or examples would be greatly appreciated!

Thanks in advance!
