Chapter 1: Introduction

Introduction to the Router

Thank you for choosing the Linksys 10/100 4-Port VPN Router. The Router lets multiple computers in your office share an Internet connection. The dual Internet ports let you connect a second Internet line as a backup, or you can use both Internet ports at the same time, allowing the Router to manage bandwidth demands for maximum efficiency.
The Router features a built-in, 4-port, full-duplex, 10/100 Ethernet switch to connect four computers directly, or you can connect more switches to expand your network. For remote connections, up to 50 remote office or traveling users can securely connect to your office network using the Router’s Virtual Private Network (VPN) capability.
Use the browser-based utility to configure settings and run convenient wizards that will help you set up the Router and its access rules.
For an IPSec VPN tunnel, the VPN Router and any computer with the built-in IPSec Security Manager (Windows 2000 and XP) can create a VPN tunnel using IPSec (Windows Vista uses a similar utility). Other Windows operating systems require additional, third-party VPN client software applications that support IPSec to be installed.
NOTE: The 10/100 4-Port VPN Router supports
IPSec VPN client software, including the Linksys QuickVPN software. (For more information, refer to “Appendix B: Linksys QuickVPN for Windows 2000, XP, or Vista”.)
For a PPTP VPN tunnel, the 10/100 4-Port VPN Router and any computer running Windows 2000 or XP can create a VPN tunnel using PPTP.

VPN Examples

The following are examples of a VPN tunnel between two VPN routers and a VPN tunnel between a computer using VPN client software and a VPN router.

VPN Router to VPN Router

Introduction to VPNs

A VPN 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. This establishes a private network that can send data securely between these two locations or networks.
The private network is established by creating a “tunnel”. A VPN tunnel connects the two computers or networks and allows data to be transmitted over the Internet as if it were still within those networks. A VPN tunnel uses industry-standard encryption and authentication techniques to secure the data sent between the two networks.
Virtual Private Networking was created as a cost-effective alternative to using a private, dedicated, leased line for a private network. It can be used to create secure networks linking a central office with branch offices, telecommuters, and/or professionals on the road.
There are two basic ways to create a VPN connection:
VPN Router to VPN Router
For example, at home, a telecommuter uses his VPN Router for his always-on Internet connection. His Router is configured with his office’s VPN settings. When he connects to his office’s router, the two routers create a VPN tunnel, encrypting and decrypting data. As VPNs use the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection to the central office’s network, as if he were physically connected.

The VPN Router creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure. A computer with VPN client software can be one of the two endpoints.

Computer (using VPN client software) to VPN Router

The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling businesswoman connects to her Internet Service Provider (ISP). Her notebook computer has VPN client software that is configured with her office’s VPN settings. She accesses the VPN client software and connects to the VPN Router at the central office. As VPNs use 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.

Forwarding

Port Range Forwarding
Port forwarding can be used to set up public services on your network. When users from the Internet make certain requests on your network, the Router can forward those requests to computers equipped to handle the requests. If, for example, you set the 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.
NOTE: You must disable the Router’s DHCP
function to use port forwarding.
You may use this function to establish a web server or FTP server via an IP gateway. Make sure that you enter a valid IP address. (You may need to establish a static IP address in order to properly run an Internet server.) For added security, Internet users will be able to communicate with the server, but they will not actually be connected. The packets will simply be forwarded through the Router.

Setup > One-to-One NAT
One-to-One NAT (Network Address Translation) creates a relationship that maps valid external IP addresses to internal IP addresses hidden by NAT. A device with an internal IP address may be accessed at the corresponding external valid IP address.
To create this relationship, define internal and external IP address ranges of equal length. Once the relationship is defined, the device with the first internal IP address is accessible at the first IP address in the external IP address range, and so forth.
For example, you have a Local Area Network (LAN) for which the ISP has assigned the IP address range of 209.19.28.16 to 209.19.28.31, with 209.19.28.16 used as the Wide Area Network (WAN) or NAT public IP address of the Router. The address range of 192.168.168.1 to 192.168.168.255 is used for the devices on the LAN. With One-to-One NAT, the devices with the internal IP addresses of 192.168.168.2 to 192.168.168.15 may be accessed at the corresponding external IP addresses.
NOTE: The Router’s WAN IP address should not
be included in the range you specify.

Private Range Begin Enter the starting IP address of the
internal IP address range. This is the IP address of the first device that can be accessed from the Internet.
Public Range Begin Enter the starting IP address of the

Advanced Routing

Dynamic Routing
The Router’s dynamic routing feature can be used, so the Router will automatically adjust to physical changes in the network’s layout. Using the dynamic RIP protocol, the Router calculates the most efficient route for the network’s data packets to travel between the source and the destination, based upon the shortest paths. The RIP protocol regularly broadcasts routing information to other routers on the network. It determines the route that the network packets take based on the fewest number of hops between the source and the destination.
Working Mode Select Gateway mode if the Router
is hosting your network’s connection to the Internet. Select Router mode if the Router exists on a network with other routers, including a separate network gateway that handles the Internet connection. In Router mode, any computer connected to the Router will not be able to connect to the Internet unless you have another router function as the gateway.
RIP (Routing Information Protocol) To use dynamic
routing for communication of network data, select
Enabled. Otherwise, keep the default, Disabled.
Receive RIP versions To use dynamic routing for
reception of network data, select the protocol you want:
None, RIPv1, RIPv2, or Both RIP v1 and v2.
Transmit RIP versions To use dynamic routing for
transmission of network data, select the protocol you want:
None, RIPv1, RIPv2 - Broadcast, or RIPv2 - Multicast.

Static Routing
If the Router is connected to more than one network or there are multiple routers installed on your network, it may be necessary to set up static routes. The static routing function determines the path that data follows over your network before and after it passes through the Router. You can use static routing to allow different IP domain users to access the Internet through the Router.
Static routing is a powerful feature that should be used by advanced users only. In many cases, it is better to use dynamic routing because it enables the Router to automatically adjust to physical changes in the network’s layout.

NOTE: Static routing is an advanced feature.
Create these routes with care.
To create a static route entry, enter the following information:
Destination IP Enter the network address of the remote
LAN segment. For a standard Class C IP domain, the network address is the first three fields of the Destination LAN IP, while the last field should be 0.
Subnet Mask Enter the subnet mask used on the
destination LAN IP domain. For Class C IP domains, the subnet mask is 255.255.255.0.
Default Gateway Enter the IP address of the router of the
network, for which this static route is created. For example, if this network is connected to the local router’s LAN port through another router, use the WAN IP address of that router.
Hop Count Enter the appropriate value (maximum is 15).
This indicates the number of nodes that a data packet passes through before reaching its destination. A node is any device on the network, such as a computer or router.
Interface Select the appropriate interface. The Interface
tells you whether your network is on the LAN, WAN1, or WAN2/DMZ. If the gateway router is on a LAN port, then select LAN. If you’re connecting to another network through the Internet, select the appropriate WAN port option.

DHCP > Setup

The Router can be used as a DHCP (Dynamic Host Configuration Protocol) server on your network. A DHCP server automatically assigns available IP addresses to computers on your network. If you choose to enable the DHCP server option, all of the computers on your LAN must be set to obtain an IP address automatically from a DHCP server. (By default, Windows computers are set to obtain an IP automatically.)
If the Router’s DHCP server function is disabled, do one of the following:
Configure the IP address, subnet mask, and DNS settings of every computer on your network. (Make sure you do not assign the same IP address to different computers.)
Set up a stand-alone DHCP server with the Router as the default gateway.
