ActiveUpdate Server as the OfficeScan Agent Update Source
When OfficeScan agents download updates directly from the Trend Micro ActiveUpdate server, you can limit the download to only the pattern files to reduce the bandwidth consumed during updates and speed up the update process.
Scan engines and other components are not updated as frequently as pattern files, which is another reason to limit the download to only the pattern files.
A pure IPv6 agent cannot update directly from the Trend Micro ActiveUpdate Server. A dual-stack proxy server that can convert IP addresses, such as DeleGate, is required to allow the OfficeScan agents to connect to the ActiveUpdate server.
