The following table describes the labels in this screen. 

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 
do any configurations directly to the ZyWALL (using either the web configurator, SMT 
menus or commands) without notifying the Vantage CNM administrator.

If you have NAT routers or firewalls between the ZyWALL and the Vantage CNM server, you 
must configure them to forward TCP ports 8080 (HTTP), 443 (HTTPS) and 20 and 21 (FTP). 
They must also forward UDP ports 1864 and 1865.

Vantage CNM is disabled on the device by default. Click ADVANCED > REMOTE MGMT 
> CNM to configure your device’s Vantage CNM settings.
