A registry key was added to 2106 VDA which passes the complete device BIOS id which should handle a scenario where the hardware ID presented to the VDA is the VPN NIC hardware id.
 
This feature is disabled by default on the VDA and can be enabled as per the following steps:
 
Create the following registry value on the VDA (if MCS or PVS provisioned VMs please update master image/ vdisk in private mode and update catalog).

Problem Cause

When using certain VPN solutions the device hardwareid passed to the license server will be a common hardwareid assigned to the VPN

When accessing a site configured to consume concurrent licensing a licence will be issued based on the endpoint hardwareid during first session launch then returned to the license pool when all sessions launched via this hardware ID end.
Since all clients connecting via this VPN will have the same hardware ID a single license will be issued to the first device and any other device which connects via the same VPN will consume the same concurrent license.

i.e. if 200 clients connect to the same site via a VPN which uses a common hardware ID - 1 concurrent license will be consumed
