    HAPTER NTRODUCTION Congratulations on your purchase of the ADSL2 Barricade , hereafter referred to as the “Barricade.” We are proud to provide you with a powerful yet simple communication device for connecting your local area network (LAN) to the Internet. For those who want to surf the Internet in the most secure way, the Barricade provides a convenient and powerful solution.

  • Page 16: Applications

    NTRODUCTION • NAT also enables multi-user Internet access via a single user account, and virtual server functionality (providing protected access to Internet services such as web, FTP, email, and Telnet) • QoS (Quality of Service) support • Easy setup through a web browser on any operating system that supports TCP/IP Applications Many advanced networking features are provided by the Barricade:...
  • Page 17 PPLICATIONS • Virtual Server If you have a fixed IP address, you can set the Barricade to act as a virtual host for network address translation. Remote users access various services at your site using a constant IP address. Then, depending on the requested service (or port number), the Barricade can route the request to the appropriate server (at another internal IP address).
