Blocking Keywords, Sites, and Services
The modem router provides a variety of options for blocking Internet-based content and
communications services. With its content filtering feature, the modem router prevents
objectionable content from reaching your PCs. You can control access to Internet content by
screening for keywords within Web addresses. Content filtering options include:
• Keyword blocking of HTTP traffic.
• Outbound service blocking. Limits access from your LAN to Internet locations or services that
you specify as off-limits.
• Denial of service (DoS) protection. Detects and thwarts denial of service (DoS) attacks such as
Ping of Death, SYN flood, LAND attack, and IP spoofing.
• Blocking unwanted traffic from the Internet to your LAN.
The following section explains how to configure your
modem router to perform these
functions.
