Introduction

Thank you for choosing the Cisco RVS4000 4-Port Gigabit Security Router with VPN. The 4-Port Gigabit Security Router with VPN 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.

The 4-Port Gigabit Security Router with VPN also features a built-in 4-Port fullduplex 10/100/1000 Ethernet switch to connect four PCs directly, or you can connect more hubs and switches to create as big a network as you need.

The Virtual Private Network (VPN) capability creates encrypted “tunnels” through the Internet, allowing up to 5 remote offices and 5 traveling users to securely connect into your office network from off-site. Users connecting through a VPN tunnel are attached to your company’s network — with secure access to files, email, and your intranet — just as if they were in the building. You can also use the VPN capability to allow users on your small office network to securely connect out to a corporate network. The QoS features provide consistent voice and video quality throughout your business.

The 4-Port Gigabit Security Router with VPN can serve as a DHCP Server, and has a powerful SPI firewall and Intrusion Prevention System (IPS) to protect your PCs against intruders and most known Internet attacks. You can configure the router to filter internal users’ access to the Internet, and has IP and MAC address filtering so you can specify exactly who has access to your network. Configuration is a snap with the web browser-based configuration utility.

This administration guide will give you all the information you need to connect, set up, and configure your router.

Networking and Security Basics

This chapter describes networking and security basics. It includes these sections:

•An Introduction to LANs, page 9

•The Use of IP Addresses, page 10

•The Intrusion Prevention System (IPS), page 11

An Introduction to LANs

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.

The router’s Network Address Translation (NAT) technology protects your network of PCs so users on the Internet cannot “see” your PCs. This feature keeps your LAN remains private. The router protects your network by inspecting the first packet received through the Internet port before delivering it to the final destination on one of the Ethernet ports. The router inspects Internet port services like the web server, ftp server, or other Internet applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side.

Networking and Security Basics	2
The Use of IP Addresses

The Use of IP Addresses

IP stands for Internet Protocol. Every device in an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its location, or address, on the network. This applies to both the Internet and LAN connections.

There are two ways of assigning IP addresses to your network devices.

A static IP address is a fixed IP address that you assign manually to a PC or other device on the network. Since a static IP address remains valid until you disable it, static IP addressing ensures that the device assigned it will always have that same IP address until you change it. Static IP addresses are commonly used with network devices such as server PCs or print servers.

If you use the router to share your cable or DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the router. You can get the information from your ISP.

A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called dynamic because they are only temporarily assigned to the PC or other device. After a certain time period, they expire and may change. If a PC logs onto the network (or the Internet) and its dynamic IP address has expired, the DHCP server will assign it a new dynamic IP address.

A DHCP server can either be a designated PC on the network or another network device, such as the router. By default, the router’s Internet Connection Type is

Obtain an IP automatically (DHCP).

The PC or network device that obtains an IP address is called the DHCP client. DHCP frees you from the requirement to assign an IP address manually when a new user is added to your network.

For DSL users, many ISPs may require you to log on with a user name and password to gain access to the Internet. This is a dedicated, high-speed connection type called Point to Point Protocol over Ethernet (PPPoE). PPPoE is similar to a dial-up connection, but PPPoE does not dial a phone number when establishing a connection. 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 on your network, you MUST disable one of the two DHCP servers. If you run more than one DHCP server on your network, you will experience network errors, such as conflicting IP addresses. To disable DHCP on the router, see the Basic Setup section in Chapter 5, “Setting Up and

Configuring the Router.”

Networking and Security Basics	2
The Intrusion Prevention System (IPS)

NOTE Since the router is a device that connects two networks, it needs two IP addresses—one for the LAN, and one for the Internet. In this Administration Guide, you’ll see references to the “Internet IP address” and the “LAN IP address”.

Since the router uses NAT technology, the only IP address that can be seen from the Internet for your network is the router’s Internet IP address. However, even this Internet IP address can be blocked so the router and network seem invisible to the Internet.

The Intrusion Prevention System (IPS)

IPS is an advanced technology to protect your network from malicious attacks. IPS works together with your SPI Firewall, IP Based Access Control List (ACL), Network Address Port Translation (NAPT), and Virtual Private Network (VPN) to achieve the highest level of security. IPS works by providing real-time detection and prevention as an in-line module in a router.

The RVS4000 has hardware-based acceleration for real-time pattern matching to detect malicious attacks. It actively filters and drops malicious TCP/UDP/ICMP/ IGMP packets and can reset TCP connections. This feature prevents network worm attacks against client PCs and servers with various operating systems including Windows, Linux, and Solaris. However, this system does not prevent viruses contained in email attachments.

The P2P (Peer-to-Peer) and IM (Instant Messaging) control allows the system administrator to prevent network users from using those protocols to communicate with people over the Internet. This helps the administrators to set up company policies on how to use the Internet bandwidth wisely.

The signature file is the heart of the IPS system. It is similar to the Virus definition file on your PC’s Anti-Virus software. IPS uses this file to match against packets coming into the router and performs actions accordingly. The RVS4000 has a signature file that contains 1000+ rules, which cover these categories: DDoS, Buffer Overflow, Access Control, Scan, Trojan Horse, Misc., P2P, IM, Virus, Worm, and Web Attacks.

Customers are encouraged to update their IPS signature file regularly to prevent any new types of attacks on the Internet.

Planning Your Virtual Private Network (VPN)

This chapter provides information for planning your VPN. It includes these sections:

•Why do I need a VPN?, page 13

•What is a VPN?, page 15

Why do I need a VPN?

Computer networking provides a flexibility not available when using an archaic, paper-based system. With this flexibility, however, comes an increased risk in security. Firewalls address this risk. Firewalls help to protect data inside of a local network. But what do you do when information leaves your local network, when emails go to their destination, or when you connect to your company’s network from a hotel or remote office? How is your data protected?

A VPN can help. VPNs are called Virtual Private Networks because they secure data moving outside of your network as if it were still within that network.

When data travels across the Internet from your computer, it is always open to attacks. You may already have a firewall, which helps protect data in your network from being corrupted or intercepted by entities outside of your network. When data moves outside of your network—when you send data to someone via email or communicate with an individual over the Internet—the firewall no longer protects your data.

At this point, your data becomes open to hackers who use a variety of methods to steal not only the data you transmit but also your network login and security data. Some of the most common methods are described in on the next page.

Cisco RVS4000 Security Router with VPN Administrator Guide

13

Planning Your Virtual Private Network (VPN)	3
Why do I need a VPN?

1) MAC Address Spoofing

Packets transmitted over a network, either your local network or the Internet, are preceded by a packet header. These packet headers contain both the source and destination information for that packet to transmit efficiently. A hacker can use this information to spoof (or fake) a MAC address allowed on the network. With this spoofed MAC address, the hacker can also intercept information meant for another user.

2) Data Sniffing

Hackers use data “sniffing” to obtain network data as it travels through unsecured networks, such as the Internet. Tools for just this kind of activity, such as protocol analyzers and network diagnostic tools, are often built into operating systems and allow the data to be viewed in clear text.

3) Man in the middle attacks

Once the hacker has either sniffed or spoofed enough information, he can now perform a “man in the middle” attack. Hackers use this attack when data is transmitted from one network to another, by rerouting the data to a new destination. Even though the data never reaches its intended recipient, it appears successful to the person who sent the data.

These are only a few of the methods hackers use, and they are always developing more. Without the security of your VPN, your data is constantly open to such attacks as it travels over the Internet. Data travelling over the Internet often passes through many different servers around the world before reaching its final destination. That’s a long way to go for unsecured data and this is when a VPN serves its purpose.

Planning Your Virtual Private Network (VPN)	3
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. This establishes a private network that can send data securely between these two locations or networks.

This is done by creating a “tunnel”. A VPN tunnel connects the two PCs or networks and allows data to be transmitted over the Internet as if it were still within those networks. Not a literal tunnel, it is a connection secured by encrypting the data sent between the two networks.

VPN was created as a cost-effective alternative to using a private, dedicated, leased line for a private network. Using industry standard encryption and authentication techniques—IPSec, short for IP Security—VPN creates a secure connection that, in effect, operates as if you were directly connected to your local network. You can use VPN to create a secure network that links a central office with branch offices, telecommuters, and/or professionals on the road (travelers can connect to a VPN router by using any computer with the Cisco QuickVPN Client software).

There are two basic ways to create a VPN connection:

•VPN router to VPN router

•Computer (using the Cisco QuickVPN Client software) to VPN router

The VPN router creates a “tunnel” or channel between two endpoints, so that data transmissions between them are secure. A computer with the Cisco QuickVPN Client software can be one of the two endpoints (refer to Appendix B, “Using Cisco QuickVPN for Windows 2000, XP, or Vista”). If you choose not to run the VPN client software, any computer with the built-in IPSec Security Manager (Microsoft 2000 and XP) allows the VPN router to create a VPN tunnel by using IPSec (refer to Appendix C, “Configuring IPSec with a Windows 2000 or XP Computer”). Other versions of Microsoft operating systems require additional, third-party VPN client software applications that support IPSec to be installed.

What is a VPN?

VPN Router to VPN Router

With a VPN-router-to-VPN-router VPN, 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 utilize the Internet, distance is not a factor. While using the VPN, the telecommuter now has a secure connection to the central office’s network, as if he were physically connected. For more information, refer to Appendix D, “Gateway-to-Gateway VPN Tunnel.”

Computer (using the Cisco QuickVPN Client software) to VPN Router

In this illustration, you see an example of a computer-to-VPN router VPN. In her hotel room, a traveling businesswoman connects to her ISP. Her notebook computer has the Cisco QuickVPN Client software, which is configured with her office’s IP address. She accesses the Cisco QuickVPN Client software and connects to the VPN router at the central office. As VPNs utilize the Internet, distance is not a factor. While using the VPN, she now has a secure connection to the central office’s network, as if she were physically connected.
