this seems to be a different problem than the initial one, isn't it? Which beta version do you use? Mind to attach a snippet of the log files wireless.log and red.log?
Thank you very much, I have some more questions. The red seems to got disconnected from the asg once yesterday. Do you know why? Is it cause of your ISP (for the location of the red), or do you have plugged out the power supply, or was there an electrical power outage? Does it happen often, like once a day? How long do you have this red now? The reason I ask the last questions is that it could be a hardware issue with the flash memory.
Do you have more than one ASG/UTM or do you have another dhcp server than your UTM itself?
