To prevent MAC address duplication when systems connect through a VPN, first determine the MAC address of the VPN server. The primary way to learn the MAC address is to access one of the systems that connects through the VPN.
Ensure that you have a remote connection to systems connecting to ePO - On-prem through a VPN server.
Remotely connect to a system that uses the VPN.
Click the Trellix Agent icon to open the Trellix Agent Status Monitor.
If you don't see the Trellix Agent icon, you can run the application from a command line:
From the command prompt, change directories to this default folder:
C:\Program Files\McAfee\Common Framework\Type:
CmdAgent.exe /s
The Trellix Agent Status Monitor opens.

This process collects system properties and sends the information to the ePO - On-prem server.
From the ePO - On-prem console, select Menu → Systems → System Tree.
Locate the system and double-click the system name.
Click the System Properties tab, then click Customize on the right of the display.
From the Properties list, find MAC Address, click Move to Top, and click Save.
The MAC address appears at the top of the list.
Make note of the first six digits of the system MAC address. This is the OUI value.
Use the OUI value in the SQL Server Management Studio to update the virtual MAC vendor ID.
