OfficeScan provides a location awareness feature that determines the Web reputation policy applied to clients and the Smart Scan Server clients connect to. OfficeScan clients that can connect to the OfficeScan server or any of the reference servers are located internally, which means:
These clients will apply the Web reputation policy for internal clients.
If these clients use smart scan, they will connect to a local Smart Scan Server.
If connection cannot be established, clients will apply the Web reputation policy for external clients. If clients use smart scan, these clients will connect to the Trend Micro Global Smart Scan Server.
Trend Micro recommends enforcing a stricter Web reputation policy on external clients.
Specify whether location is based on the client computer's gateway IP address or the client's connection status with the OfficeScan server or any reference server.
Gateway IP address
If the 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.
To configure location settings:
Networked Computers > Computer Location
Choose whether location is based on Client connection status or Gateway IP and MAC address.
If you choose Client connection status, decide if you want to use a reference server. See Reference Servers for details.
If you did not specify a reference server, the client checks the connection status with the OfficeScan server when the following events occur:
Client switches from roaming to normal (online/offline) mode.
Client switches from one scan method to another. See Scan Methods for details.
Client detects IP address change in the computer.
Client restarts.
Server initiates connection verification. See Client Connection with Servers for details.
Web reputation location criteria changes while applying global settings.
Outbreak prevention policy is no longer enforced and pre-outbreak settings are restored.
If you specified a reference server, the client checks its connection status with the OfficeScan server first, and then with the reference server if connection to the OfficeScan server is unsuccessful. The client checks the connection status every hour and when any of the above events occur.
If you choose Gateway IP and MAC address:
Optionally type the MAC address. If you do not type a MAC address, OfficeScan will include all the MAC addresses belonging to the specified IP address.
Repeat step a to step c until you have all the gateway IP addresses you want to add.
Use the Gateway Settings Importer tool to import a list of gateway settings. See Gateway Settings Importer for details.
Click Save.
