Compatbility between Symantec Endpoint Protection 12.1.3 ann Palo Alto GlobalProtect

We are working on a project to install Palo Alto Network’s GlobalProtect VPN system into our network.  The project team is running into issues that they think are caused by Symantec Endpoint Protection 12.1.3.   Specifically they think Symantec is blocking access via the GlobalProtect VPN system and oher related files.

Are there any specific rules I should be putting into Endpoint Protection to allow the functioning of the Palo Alto Network GlorbalProtect product?

Thank you
