I don't know where the failure is. But it works now.... After I configured the second AP5 - the first AP5 works now too.
1) No, i configred the RED manually. DHCP and DNS i configured too. 2) The RED is in standard mode. 3) I configured the Wireless Global Interface to use the RED NIC. 4) in the RED log was only the standard Ping/Pong nothing more...
Okay there was something really messed up with the UTM ... After some reboots my manual configuration worked fine and AP5 appeared in Wireless devices.
