Introduction

Thank you for choosing the Cisco WRVS4400N Wireless-NGigabit Security Router with VPN. TheWireless-NGigabit Security Router with VPN is an advancedInternet-sharingnetwork solution for your small business needs. WRVS4400N lets multiple computers in your office share an Internet connection through both wired and wireless connections.

The WRVS4400N wireless router features a built-in4-Portfull-duplex10/100/ 1000 Ethernet switch, which allows you to connect four personal computers directly, or you can connect more hubs and switches to create as big a network as you need.

You can use the WRVS4400N wireless router as an intranet router to aggregate traffic to a company backbone network.

The WRVS4400N wireless router has a built-inaccess point that supports the latest 802.11n draft specification by IEEE. The WRVS4400N wireless router also supports 802.11g and 802.11b clients in a mixed environment.

The built-inaccess point can support an 11n data rate of up to 300 Mbps. In addition to having a higher data rate, 802.11n technology also promises longer coverage by using multiple antennas to transmit and receive data streams in different directions.

The Cisco WRVS4400N Wireless-NGigabit Security Router with VPN is equipped with advanced security technologies like Intrusion Prevention System (IPS), Stateful Packet Inspection (SPI) Firewall, IP based Access List (IP ACL), and Network Address Port Translation (NAPT, also called NAT as a more generic term).

These technologies work together by providing self-defensivestrategy. They identify, classify, and stop malicious attack traffic in real time while passing through the WRVS4400N wireless router.

The SPI Firewall provides deep packet inspection to analyze packets in network layer (IP) and transport layer (TCP, UDP) to block illegal packet transactions. You can also use IP based ACL to limit traffic to a specific source, destination and protocol.

NAPT allows you to open specific TCP/UDP port numbers to the Internet to provide limited service while minimizing harmful traffic at the same time.

The Virtual Private Network (VPN) capability is another security feature that creates encrypted “tunnels” through the Internet, allowing up to five remote offices and five 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, e-mail,and your intranet 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 of the Cisco WRVS4400N Wireless-NGigabit Security Router with VPN provide consistent voice and video quality throughout your business.

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