Hi Kristian,

Thank you for looking so deep into this. I'm gonna try your configs
tomorrow or in the weekend. But there are 2 things that comes into
mind.

The configuration guide "Guidelines for Repeaters" point 4 says:
"Repeater access points support only the native VLAN. You cannot
configure multiple VLANs on a repeater access point.". !??! (Still
this is for 12.3(8) which is in the Lab, I can see you are running a
12.4 code)

And the IPX WB1 Lab 3.8 solves this in a different way, one SSID (not
on bridge-group1). Did Jason use 12.3 or 12.4 code?

Anyone how can comment on this issue? Join the battle Wireless Genies :o)
