• Your ZyWALL can act as an SNMP agent, which allows a manager station to
manage and monitor the ZyWALL through the network. Use the System >
SNMP screen (see Section 50.11 on page 866 ) to configure SNMP settings,
including from which zones SNMP can be used to access the ZyWALL. You can
also specify from which IP addresses the access can come.
• Connect an external serial modem to the AUX port to provide a management
connection in case the ZyWALL’s other WAN connections are down. Use the
System > Dial-in Mgmt. screen (see Section 50.12 on page 870 ) to configure
the external serial modem.
• Vantage CNM (Centralized Network Management) is a browser-based global
management tool that allows an administrator to manage ZyXEL devices. Use
the System > Vantage CNM screen (see Section 50.13 on page 872 ) to allow
your ZyWALL to be managed by the Vantage CNM server.
• Use the System > Language screen (see Section 50.14 on page 875 ) to set a
language for the ZyWALL’s Web Configurator screens.
Note: See each section for related background information and term definitions.
