The AP5 arrived today. I have connected it with a RED10 rev.3.
The RED10 is connected to a ASG320 with Software 8.305 and it does not seem to work.
So i have to wait for the UTM V9 Update.... :-(
Is the RED configured for split or full (unified) tunnel? If split, don't forget to add 1.2.3.4 to the split networks list, so that it knows to forward the traffic to the ASG.
