Blocking Sites and Keywords

The router provides a variety of options for blocking Internet-based content and

communications services. With its content filtering feature, the 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 DoS attacks such as Ping of

Death, SYN flood, LAND attack, and IP spoofing.

• Blocking unwanted traffic from the Internet to your LAN.
