Full Routing on Both the ADSL and 10/100 WAN Port

You can install, configure, and operate the DGFV338 to take full advantage of a variety of routing
options on both the DSL and broadband WAN ports, including:
• Internet access via either the internal ADSL modem or through the Ethernet port connected to
an external modem.
• Auto Rollover Mode between the internal ADSL modem and the external 10/100 ethernet
WAN port. If the primary connection fails, the DGFV338 can automatically establish a backup
connection via the secondary connection.

A Powerful, True Firewall with Content Filtering

DGFV338 is a true firewall, using stateful packet inspection to defend against attacks. Its firewall
features include:
• 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 DGFV338 will log security events such as blocked incoming
traffic, attacks, and administrator logins. You can configure the firewall to email the log to you
at specified intervals. You can also configure the firewall to send immediate alert messages to
your email address or email pager whenever a significant event occurs.
• With its URL keyword filtering feature, the DGFV338 prevents objectionable content from
reaching your PCs. The firewall allows you to control access to Internet content by screening
for keywords within Web addresses. You can configure the firewall to log and report attempts
to access objectionable Internet sites.
