you need one WRVS4400N for each subnetwork and you can connect all the WAN ports to a second level Router or switch to the Internet. The Router protects your network by inspecting the first packet coming in through the Internet port before delivery to the final destination on one of the Ethernet ports. This is how your LAN remains private.Wireless-N Gigabit Security Router with VPN Chapter 2: Networking and Security Basics An Introduction to LANs A Router is a network device that connects multiple networks together and forward traffic based on IP destination of each packet. The Router’s Network Address Port Translation (NAPT or NAT) technology protects your network of PCs so users on the Internet cannot “see” your PCs. The following diagram shows an example that consists of two levels of routers and multiple LANs inter-connected together. You can use any wired router in the Linksys family. The Router inspects Internet port services like the web server. This usually applies to a medium-sized or larger company where you want to divide your network into multiple IP subnets to increase the intranet throughput and reduce the size of the IP broadcast domain and its interference. e. if allowed.g. or other Internet applications. The second level router can connect to dedicated Server PCs or routers that aggregates traffic from different LANs. You can use one public IP address from the ISP through WAN port and use the router’s Network Address Translation (NAT) technology to share this single IP address among all the users. it will forward the packet to the appropriate PC on the LAN side. Note that the second level Router only forwards data packets through a wired network so you don’t have to use the Wireless-N Gigabit Security Router. RVS4000. LAN: the computers and networking products that make up your local network Chapter 2: Networking and Security Basics An Introduction to LANs 4 . The Wireless-N Gigabit Security Router can connect your local area network (LAN) or a group of PCs interconnected in your home or office to the Internet. which has 4 LAN ports and 1 WAN port. In this case. Multiple Wireless-N Gigabit Security Routers can also be used to connect multiple LANs together. and. ftp server. The wireless network is only available at the first level of router to provide end user connections. NAT (Network Address Translation): NAT technology translates IP addresses of a local area network to a different IP address for the Internet.

requires an IP address to identify its location. Every device in an IP-based network. In this User Guide.” Since the Router uses NAT technology. on the network. This applies to both the Internet and LAN connections. and routers. NOTE: Since the Router is a device that connects two networks. including PCs. or address. print servers. it needs two IP addresses—one for the LAN. even this Internet IP address can be hidden on the Internet by suppressing PING response. the only IP address that can be seen from the Internet for your network is the Router’s Internet IP address. There are two ways of assigning IP addresses to your network devices. you’ll see references to the “Internet IP address” and the “LAN IP address. 5 Chapter 2: Networking and Security Basics The Use of IP Addresses .Wireless-N Gigabit Security Router with VPN Figure 2-1: Example network The Use of IP Addresses IP stands for Internet Protocol. and one for the Internet. However.

If you run more than one DHCP server on your network. Static IP addresses are commonly used with dedicated network devices such as server PCs or print servers. By default. the DHCP server will assign it a new dynamic IP address. assign temporary IP addresses to the other network devices. If so. Since a user’s PC is moving around in a network and is being powered on or off. you MUST disable one of the two DHCP servers. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network. Since a static IP address remains valid until you disable it. the Router’s Internet Connection Type is Obtain an IP automatically (DHCP). DHCP (Dynamic Host Configuration Protocol): a protocol that lets one device on a local network. Dynamic IP address: a temporary IP address assigned by a DHCP server. After a certain time period. contact your ISP to find out if they have assigned a static IP address to your account. many ISPs may require you to log on with a user name and password to gain access to the Internet. A DHCP server can either be located on a designated PC on the network or another network device. A DHCP server is running on the LAN side to provide services. such as the Router. You can get the information from your ISP. static IP addressing ensures that the device assigned it will always have that same IP address until you change it. If you already have a DHCP server running on your network. For DSL users.” Static IP address: a fixed address assigned to a computer or device that is connected to a network. This is a dedicated. A dynamic IP address is automatically assigned to a device on the network. To disable DHCP on the Router. This IP address is called dynamic because it is only temporarily assigned to the PC or other device. such as conflicting IP addresses. you will need that static IP address when configuring the Router. If you use the Router to share your cable or DSL Internet connection. it expires and may change. it does not require a dedicated IP address that could be a precious resource in your network. you will experience network errors.Wireless-N Gigabit Security Router with VPN A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. By default. a DHCP server is enabled on the Router. a DHCP client is running on a WAN port for most configurations. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired. refer to the Basic Setup section in “Chapter 6: Setting Up and Configuring the Router. known as a DHCP server. Chapter 2: Networking and Security Basics The Use of IP Addresses 6 . typically computers. which establishes a PPP session with an ISP server through the DSL connection. The PC or network device obtaining an IP address is called the DHCP client. Most ISPs use dynamic IP addresses for their customers. high-speed connection type called Point-to-Point Protocol over Ethernet (PPPoE). The server will also provide the Router with a dynamic IP address to establish a connection to the Internet. For this Wireless-N Router. PPPoE is similar to a dial-up connection.

IP Based Access List (IP ACL). The Wireless-N Security Router has hardware-based acceleration for real-time pattern matching for malicious attacks. and Virtual Private Network (VPN) to achieve the highest amount of securities. IPS works by providing real-time detection and prevention as an in-line module in a router. This protects your client PCs and servers running various operating systems including Windows. It actively filters and drops malicious TCP/UDP/ICMP/IGMP packets and can reset TCP connections. However. Network Address Port Translation (NAPT). this system does not prevent viruses attached emails.

But what do you do once information is sent outside of your local network. the hacker can also intercept information meant for another user. A hacker can use this information to spoof (or fake) a MAC address allowed on the network. either your local network or the Internet. but once data moves outside of your network—when you send data to someone via e-mail or communicate with an individual over the Internet—the firewall will no longer protect that data. or when you have to connect to your company's network when you are out on the road? How is your data protected? That is when a VPN can help. 3) Man in the middle attacks Once the hacker has either sniffed or spoofed enough information. This is why firewalls were first introduced. Firewalls help to protect data inside of a local network. such as protocol analyzers and network diagnostic tools. VPNs are called Virtual Private Networks because they secure data moving outside of your network as if it were still within that network. At this point. Some of the most common methods are as follows: 1) MAC Address Spoofing Packets transmitted over a network. 2) Data Sniffing Data “sniffing” is a method used by hackers to obtain network data as it travels through unsecured networks. your data becomes open to hackers using a variety of methods to steal not only the data you are transmitting but also your network login and security data. when data is being transmitted from one network to another.Wireless-N Gigabit Security Router with VPN Chapter 3: Planning Your Virtual Private Network (VPN) Why do I need a VPN? Computer networking provides a flexibility not available when using an archaic. Tools for just this kind of activity.

There are two popular ways to establish a secured tunnel over the Internet — IPsec (IP Security) and SSL (Secure Sockets Layer). Using industry standard encryption and authentication techniques—IPsec. This is done by creating a “tunnel”. your data is constantly open to such attacks as it travels over the Internet. it appears that way to the person sending the data. so that data transmissions between them are secure. Not a literal tunnel. That's a long way to go for unsecured data and this is when a VPN serves its purpose. Virtual Private Networking can be used to create secure networks linking a central office with branch offices. leased line for a private network. These are only a few of the methods hackers use and they are always developing more. VPN was created as a cost-effective alternative to using a private. This establishes a private network that can send data securely between these two locations or networks. any computer with the built-in IPsec Security Manager (Microsoft 2000 and XP) allows the VPN Router Chapter 3: Planning Your Virtual Private Network (VPN) What is a VPN? encryption: encoding data transmitted in a network ip (internet protocol): a protocol used to send data over a network software: instructions for the computer IMPORTANT: You must have at least one VPN Router on one end of the VPN tunnel. is a connection between two endpoints—a VPN Router.

Static Routing
Sometimes you will prefer to use static routes to build your routing table instead of using dynamic routing protocols. Static routes do not require CPU resources to exchange routing information with a peer router. You can also use static routes to reach peer routers that do not support dynamic routing protocols. Static routes can be used together with dynamic routes. Be careful not to introduce routing loops in your network. To set up static routing, you should add route entries in the routing table that tell the Router where to forward packets to specific IP destinations.

Enter the following data to create a static route entry: 1. Select Set Number. Select the set number (routing table entry number) that you wish to view or configure. If necessary, click Delete This Entry to clear the entry. 2. Destination IP Prefix. 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; the last field should be zero. 3. 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. 4. Next Hop Router. Enter the next hop router used to reach your destination LAN, as defined in Step (2). 5. Hop Count (max. 15). This value gives the number of routers that a data packet passes through before reaching its destination. It is used to define the priority on which route to use if there is a conflict between a static route and dynamic route. Figure 6-15: Setup - Advanced Routing (Routing Table)

Frequently Asked Questions
What is the maximum number of IP addresses that the Router will support? The Router will support up to 253 IP addresses if the subnetmask is set to 255.255.255.0. Is IPSec Passthrough supported by the Router? Yes, enable or disable IPSec Passthrough on the VPN => VPN Pass Through tab. Where is the Router installed on the network? In a typical environment, the Router is installed between the cable/DSL modem and the LAN. Plug the Router into the cable/DSL modem’s Ethernet port. Does the Router support IPX or AppleTalk? No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but those protocols cannot connect from the Internet to the LAN.

Appendix A: Troubleshooting Frequently Asked Questions

Wireless-N Gigabit Security Router with VPN

What is Network Address Translation and what is it used for? Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP. Does the Router support any operating system other than Windows 98, Millennium, 2000, or XP? Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems. I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do? If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can also use a port forwarding range of 7777 to 27900. If you want to use the UT Server Admin, forward another port (8080 usually works well but is used for remote admin. You may have to disable this.), and then in the [UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and ServerName to the IP assigned to the Router from your ISP. Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP address? It depends on which network game or what kind of game server you are using. For example, Unreal Tournament supports multi-login with one public IP. How do I get Half-Life: Team Fortress to work with the Router? The default client port for Half-Life is 27005. The computers on your LAN need to have “+clientport 2700x” added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at the same time, even if on the same LAN (not a problem with 1.0.1.3). As far as hosting games, the HL server does not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer. How can I block corrupted FTP downloads? If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP program. The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the screen. What do I need to do? Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s
