5.5
Firewall
The DCM-604 provides built-in firewall functions, enabling you to protect the
system against denial of service (DoS) attacks and other unwelcome or
malicious accesses to your LAN.
5.5.1 Web Filter
This page allows certain Web-oriented cookies, java scripts, and pop-up windows to
be blocked by the firewall. A list of "trusted computers" can also be defined that are
not subject to any filters configured. Specific Firewall features can also be enabled. It
is highly recommended that the Firewall is left enabled at all times for protection
against Denial of Service attacks. Go to the Parental Control page to block internet
access to specific sites.
5.5.2 Local Log
The Local Log page allows you to configure the firewall event log reported via
email alert, and these attack records are also visible in the table on the bottom
of this page.
