  • Page 15: Introduction

    Congratulations on your purchase of the ADSL2 Barricade 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, this router provides a convenient and powerful solution.

  • Page 17 • 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).
  • Page 18 NTRODUCTION • Point-to-Point Tunneling Protocol — Provides a secure tunnel for remote client access to a PPTP security gateway. PPTP includes provisions for call origination and flow control required by ISPs. • L2TP merges the best features of PPTP and L2F — Like PPTP, L2TP requires that the ISP’s routers support the protocol.
