SD RED 20 wifi module registers on wrong firewall

Hi there,

I've got a SD RED 20 with integrated wifi module, which was connected to a Firewall in Germany before. I set up a new RED config and shipped the Box to our branch in the USA. The Firewalls in USA and Germany are connected through IPSEC-Tunnel. If I start the USA RED it connects itself to the USA Firewall, which is correct, but the accesspoint shows up on the Firewall in Germany. Is there any configuration needed for the wifi module or do I just need to delete it on Germany Firewall?

Thanks for advice or any help...
