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.
1
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.

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 T ranslation (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 po rt 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
The Use of IP Addresses
The Use of IP Addresses
IP stands for Int ernet Pr otocol. Ev ery 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 co nfiguring the router. You can get the
information from your ISP.
2
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.”
Cisco RVS4000 Security Router with VPN Administrato r G uide10
Networking and Security Basics
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 Int ernet. 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 f or y our network is the r outer’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 y our 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.
2
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?, page13
•What is a VPN?, page15
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. Y ou 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 Administrato r G uide13
Planning Your Virtual Private Network (VPN)
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
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 ar e always dev eloping
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.
Cisco RVS4000 Security Router with VPN Administrato r G uide14
Planning Your Virtual Private Network (VPN)
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 tw o 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).
3
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 AppendixB, “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.

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 offic e’s router, the t wo 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.”
