[Android Q&A, Help & Troubleshooting] Huminaotr:
Hey All,

I have a Symbol Scanner device running Android KitKat 4.4.4 with Cisco AnyConnect and the tunnel comes up when I log into AnyConnect, but I do not see any receive traffic on our firewall. In fact using Google Datally I don't even see traffic on the hotspot that the Android device is connected to. I do not have root level permissions as these are configured by Zebra/Symbol at the factory and they have been less than helpful so far.

Here is a snippet of logs I'm seeing, but I'm unsure if I'm seeing anything telling:

It appears to me that the network is completely disabled when AnyConnect is running since when I take a cap using RxLogger (Zebra's built in packet cap app) there is nothing in the capture. This is not the case when AnyConnect is not running.

Here is what has been tried already:

•	Installed various versions of Cisco AnyConnect ranging from AnyConnect 4.0.x – 4.7.x on the scanner

•	Tested AnyConnect from another Android 4.4.4 installed on a VM on my laptop with success

•	Tested AnyConnect from many other versions of Android with success from Android 5.x – 8.0

•	Tested data transfer from the Symbol scanner to the hotspot to which it’s connected with AnyConnect running (No data is transferred)

•	Tested data transfer from the Symbol scanner to the hotspot to which it’s connected without AnyConnect running (Data is transferred)

•	Tested connectivity to both Cisco FTD and Cisco ASA firewalls with the same result

•	Adjusted MTU settings within both firewalls with no success.

Thank you to anyone that can help out!
