Use the system screens to configure general ZyWALL settings. 
43.1.1  What You Can Do In The System Screens
• Use  the System > Host Name screen (
) to configure a unique 
name for the ZyWALL in your network.
• Use the System > Date/Time screen (
) to configure the date and 
time for the ZyWALL.
• Use the System > Console Speed screen (
) to configure the 
console port speed when you connect to the ZyWALL via the console port using a 
terminal emulation program.
• Use  the System > DNS screen (
) to configure the DNS (Domain 
Name System) server used for mapping a domain name to its corresponding IP address 
and vice versa.
• Use the System > WWW screen (
) to specify from which zones 
you can access the ZyWALL using HTTP or HTTPS. You can also specify which IP 
addresses the access can come from.
• Use the System > SSH screen (
) to configure SSH (Secure SHell) 
used to securely access the ZyWALL’s command line interface. You can specify which 
zones allow SSH access and from which IP address the access can come. 
• Use the System > TELNET screen (
) to configure Telnet to 
access the ZyWALL’s command line interface. Specify which zones allow Telnet access 
and from which IP address the access can come.
• Use the System > FTP screen (
) to specify from which zones FTP 
can be used to access the ZyWALL. You can also specify from which IP addresses the 
access can come. You can upload and download the ZyWALL’s firmware and 
configuration files using FTP. Please also see 
 for more 
information about firmware and configuration files.
• 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 (
) 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 (
) to configure the external serial modem.
