Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624
Introduction 2-3
M-10153-01
A Powerful, True Firewall with Content Filtering
Unlike simple Internet sharing NAT routers, the WGU624 is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
• Denial of Service (DoS) protection.
Automatically detects and thwarts DoS attacks such as Ping of Death, SYN Flood, LAND
Attack, and IP Spoofing.
• Blocks unwanted traffic from the Internet to your LAN.
• Blocks access from your LAN to Internet locations or services that you specify as off-limits.
• Logs security incidents.
The WGU624 will log security events such as blocked incoming traffic, port scans, attacks,
and administrator logins. You can configure the router to e-mail the log to you at specified
intervals. You can also configure the router to send immediate alert messages to your e-mail
address or e-mail pager whenever a significant event occurs.
• The WGU624 prevents objectionable content from reaching your PCs. The router allows you
to control access to Internet content by screening for keywords within Web addresses. You can
configure the router to log and report attempts to access objectionable Internet sites.
