21.16 Introducing Vantage CNM

Vantage CNM (Centralized Network Management) is a browser-based global management solution that allows an administrator from any location to easily configure, manage, monitor and troubleshoot ZyXEL devices located worldwide. See the Vantage CNM User's Guide for details.

If you allow your ZyWALL to be managed by the Vantage CNM server, then you should not configure the ZyWALL (using either the web configurator, SMT menus or commands) without notifying the Vantage CNM administrator.
