Wireless Access

I have a wireless network with IAP215 devices deployed over a school, but 6 of the 13 devices are connecting to the Virtual controller ( all these devices are on the same switch)

But the other devices are trying to create their own network and connect to a newly coming up VC. All the devices are in the same subnet, getting all their IP trough DHCP from the router on VLAN 1. But for some how they don’t communicate to the other VC.

I can ping from and to each other with no issues. I use HPE 1920 switches and have setup VLAN 1, 10 and 20. I have setup the ports to the devices to allow tagged 10 and 20 and untagged an vid 1.

There must be something that is blocked or so because they get all IP information from the same device without issues. I can ping them but they will not communicate to the VC.

Any Idea why this could be happening.

Make sure they all have the same version of Instant Code.

I have already did a update on all devices. So i think that is not the problem.

they all have the version 6.5.3.2

i think i figured it out. I had all the following enabled on my HPE 1920s switch:

And some of these settings where blocking the traffic between the AP's, anyone who has an idea wich setting this could be?

i figured out that is the Prevent UDP Blat Attack setting that is blocking traffic that not schould be blocked.
