Gateway IP and MAC address: If the OfficeScan client computer's gateway IP address matches any of the gateway IP addresses you specified on the Computer Location screen, the computer's location is internal. Otherwise, the computer's location is external.

Client connection status: If the OfficeScan client can connect to the OfficeScan server or any of the assigned reference servers on the intranet, the computer's location is internal. Additionally, if a computer outside the corporate network can establish connection with the OfficeScan server/reference server, its location is also internal. If none of these conditions apply, the computer's location is external.
