GlobalProtect 6.3.1 and later releases include the Intelligent Internal Host Detection parameter. This feature applies when users use the GlobalProtect app in internal host detection mode for User-ID while using 3rd party VPN for accessing private party applications. When internal host detection takes place before the 3rd party VPN establishes a tunnel, it fails to establish the User-ID. With the Enable Intelligent Internal Host Detection parameter, the GlobalProtect app can now detect Internal Host Detection in presence of 3rd party VPN agent by re-triggering network discovery until Internal Host Detection is successful.
