Administration
The FIREWALL VPN ROUTER Firewall Administration and monitoring
control is set by the System Administrator. The System Administrator can
add or modify System settings and monitoring mode. The sub Administrators
can only read System settings but not modify them. In Administration, the
System Administrator can:
(1) Add and change the sub Administrator’s names and passwords;
(2) Back up all Firewall settings into local files;
(3) Set up alerts for Hackers invasion.
What is Administration?
“Administration” is the managing of settings such as the privileges of packets
that pass through the firewall and monitoring controls. Administrators may
manage, monitor, and configure firewall settings. All configurations are “read-
only” for all users other than the Administrator; those users are not able to
change any settings for the firewall.
The three sub functions under Administrator are Administrator, Setting,
and Software Update.
Administrator: has control of user access to the firewall. He/she can
add/remove users and change passwords.
Setting: The Administrator may use this function to backup firewall
configurations and export (save) them to an “Administrator” computer or
anywhere on the network; or restore a configuration file to the FIREWALL
VPN ROUTER; or restore the firewall back to default factory settings. Under
Setting, the Administrator may enable e-mail alert notification. This will alert
Administrator(s) automatically whenever the firewall has experienced
unauthorized access or a network hit (hacking or flooding). Once enabled,
an IP address of a SMTP (Simple Mail Transfer protocol) Server is required.
Up to two e-mail addresses can be entered for the alert notifications.
Software Update: Administrators may visit distributor’s web site to
download the latest firmware. Administrators may update the FIREWALL
VPN ROUTER firmware to maximize its performance and stay current with
the latest fixes for intruding attacks.
