    Chapter 1: Introduction Welcome Thank you for choosing the 10/100/1000 4-Port VPN Router. The Linksys 10/100/1000 4-Port VPN Router is an advanced Internet-sharing network solution for your small business needs. Like any router, it lets multiple computers in your office share an Internet connection. But the 10/100/1000 4-Port VPN Router allows you to connect gigabit-equipped PCs for gigabit networking, as well as including four 10/100/1000 ports for network connectivity.

  • Page 12: Chapter 2: Networking Basics

    A Router is a network device that connects two networks together. The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet. The Router processes and regulates the data that travels between these two networks.

  • Page 13: Why Do I Need A Vpn

    It also will provide the Router with a dynamic IP address to establish a connection to the Internet. By default, a DHCP server (on the LAN side) is enabled on the Router. If you already have a DHCP server running on your network, you MUST disable one of the two DHCP servers.

  • Page 14: What Is A Vpn

    What is a VPN? A VPN, or Virtual Private Network, is a connection between two endpoints - a VPN Router, for instance - in different networks that allows private data to be sent securely over a shared or public network, such as the Internet.

  • Page 15: Figure 2-1: Vpn Router-To-Vpn Router Vpn

    As VPNs utilize the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure connection to the central office's network, as if she were physically connected. For additional information and instructions about creating your own VPN, please visit Linksys’s website at www.linksys.com.

    Chapter 5: Setting Up and Configuring the Router Overview The Router comes with a Web-based Utility that allows for easy set up and configuration. This chapter will explain all of the functions in this Utility. (You can access the web-based utility by accessing 192.168.1.1.) There are eleven main tabs in the Utility: System Summary, Setup, DHCP, System Management, Port Management, Firewall, VPN, Log, Wizard, Support, and Logout.

    The Setup screen contains all of the Router’s basic setup functions. These functions can be set from this screen but normally don’t need to be adjusted, as the Router has been designed to be used in most network settings without changing any of the default values. Some users, however, may need to enter additional information in order to connect to the Internet through an ISP (Internet Service Provider) or broadband (DSL, cable modem) carrier.

    Max Idle Time setting. 3. By selecting the Keep Alive option, the Router will keep the connection alive by sending out a few data packets at the Redial Period, so your Internet service thinks that the connection is still active.

  • Page 28: Setup Tab - Password

    The Router's default User Name and Password is admin. For greater network security, you should change the Router's password from this default. If you leave the password field blank, all users on your network will be able to access the Router simply by entering admin into the password field.

  • Page 29: Setup Tab - Dmz Host

    Port forwarding can be used to set up public services on your network. When users outside your network (i.e., from the Internet) make certain requests on your network, the Router can forward those requests to the appropriate computers equipped to handle the requests. If, for example, you set port number 80 (HTTP) to be forwarded to IP Address 192.168.1.2, then all HTTP requests from outside users will be forwarded to 192.168.1.2.

    Some ISPs require that you register a MAC address. The MAC Clone feature “clones” your network adapter's MAC address onto the Router, and prevents you from having to call your ISP to change the registered MAC address to the Router's MAC address. The Router's MAC address is a 12-digit code assigned to a unique piece of hardware for identification.

    Internet connection. When this Router is in Router Mode, you must have another router function as the gateway in order for any computer connected to the Router to be able to connect to the Internet.

To set up static routing, you should add routing entries in the Router's table that tell the device where to send all incoming packets. All of your network routers should direct the default route entry to this Router.

  • Page 35: Dhcp Tab - Setup

    DHCP Tab - Setup Setup The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server assigns available IP addresses to each computer on your network automatically. If you choose to enable the DHCP server option, you must configure all of the PCs on your LAN to connect to a DHCP server.
