I'm trying to setup an Apple Airport to work with Unifi. I setup a managed switch that strips Unifi's VLAN tag, and successfully tested it when establishing a PPPoE connection from on a Windows laptop.
Then I connected the Apple Airport to it. It didn't work, and the error message was something like the remote PPPoE server is not responding.
After that, I setup a port mirror and sniffed the traffic from the Windows laptop. This is what I found:

I upgraded the Airport to the latest firmware but the same problem persisted. Then, I connected a Macbook and tried to establish a PPPoE connection. It also failed. I didn't bother to take a packet dump here.
I have no idea how to proceed from here. Weird interoperability issue?
Soo... anyone has any ideas? [@rizvanrp] ?
I have attached a packet dump.
