A Powerful, True Firewall
Unlike simple Internet sharing NAT routers, the DG834GSP 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.
• 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 DG834GSP will log security events such as blocked incoming traffic, port scans, attacks,
and administrator logins. You can configure the modem router to email the log to you at
specified intervals. You can also configure the modem router to send immediate alert messages
to your email address or email pager whenever a significant event occurs.
