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 ( Figure 486 on page 666 ) to configure a unique
name for the ZyWALL in your network.
• Use the System > Date/Time screen ( Figure 487 on page 667 ) to configure the date and
time for the ZyWALL.
• Use the System > Console Speed screen ( Figure 489 on page 670 ) 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 ( Figure 490 on page 671 ) 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 ( Figure 497 on page 679 ) 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 ( Figure 516 on page 691 ) 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 ( Figure 520 on page 694 ) 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 ( Figure 521 on page 695 ) 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
Chapter 44 on page 705 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 ( Figure 523
on page 698 ) 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 (
Figure 524 on page 700 ) to configure the external serial modem.
