A Powerful, True Firewall

Unlike simple Internet sharing NAT routers, the CG814M Gateway 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 Denial of Service (DoS) attacks such as Ping of Death, SYN Flood, LAND Attack and IP Spoofing.

•Configurable Port Forwarding, Port Blocking, Port Triggering and DMZ provide enough flexibility for most applications.

•Blocks access from your LAN to Internet locations or services that you specify as off-limits.

•Logs security incidents

The CG814M Gateway will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the gateway to email the log to you at specified intervals. You can also configure the gateway to send immediate alert messages to your email address or email pager whenever a significant event occurs.

Content Filtering

With its content filtering feature, the CG814M Gateway prevents objectionable content from reaching your PCs. The gateway allows you to control access to Internet content by screening for keywords within Web addresses. You can configure the gateway to log and report attempts to access objectionable Internet sites.
