From the manufacturer:

ULTIMATE INTERNET CONNECTION FOR YOUR HOMES

The ADSL2+ Modem (DSL-520B) is an affordable high-performance modem ideal for your home or small office. This modem supports high download speeds,

Quality of Service (QoS), and extensive firewall protection, providing all the essentials that a home or small office would need to establish a secure and high

speed remote link to the outside world.

EXTENSIVE FIREWALL FEATURES FOR ADDED INTERNET DEFENSE

Security features prevent unauthorized access of Internet intruders from entering your home network. This modem provides firewall security using Stateful

and outbound data without concern for traffic congestion. This modem’s QoS support allows users to enjoy high ADSL transmission for applications such as

VoIP, streaming multimedia and online games.

Internet connection. It also functions as a router that provides firewall protection and QoS for secure and smooth online gaming, voice communications and

downloading of photos, files, music and video over the Internet.
