Features Benefits
Hardware-Accelerated IPSec 3DES Encryption • Delivers high-performance IPSec VPN encryption for broadband connections
• Supports Internet Key Exchange (IKE) and IPSec VPN standards for up to ten
simultaneous tunnels
• Provides WAN encryption for all users on the LAN without requiring the
configuration of individual PCs
Cisco Easy VPN Remote Provides easy deployment and maintenance of VPN connections with auto-IPSec
tunnel initiation and policy push from a Cisco VPN concentrator or server
Cisco Easy VPN Server (up to five users) Allow up to five remote VPN clients (Cisco Easy VPN Remote clients/nodes) to
terminate on the 83x0 Series routers via Cisco Easy VPN implementation
URL Filtering with WebSENSE Software and Server • Allows a network administrator to easily apply Internet use policies to permit
access only to company-approved URLs or categories of sites
• WebSENSE URL filtering software filters HTTP requests based on destination
host name, destination IP address, keywords, and user name
• WebSENSE maintains and updates a URL database of more than 20 million
sites, organized into more than 60 categories
URL Filtering with N2H2 Software and Server N2H2 is a globally deployed URL-filtering software that can filter http requests
based on destination hostname, destination IP address, and username and
password. It relies on a sophisticated URL database exceeding 15 million sites
and is organized into over 40 categories using both Internet technology and
human review.
IPSec NAT Transparency (NAT Traversal or
NAT Aware IPSec)
Allows reliable creation of VPN tunnels independent of the placement of
firewalls and NAT across multiple networks
PKI Support with Digital Certificates • Standards-based robust key management allows better network scaling and
enhanced key security
• Facilitates extranet communications
High-Quality, Secure Voice and Video
IP QoS—Low Latency Queuing (LLQ), Pre-Classify, Pre-
Fragmentation, Weighted Random Early Detection
(WRED), Committed Access Rate (CAR), and Class-Based
Traffic Shaping
• Ensures consistent response times for multiple applications by intelligently
allocating bandwidth
• Allows for classification of applications and gives the most important
applications priority use of the WAN line
• Provides congestion avoidance by throttling down certain Transmission
Control Protocol (TCP) sessions, depending on each session’s priority level
Asynchronous Transfer Mode (ATM) QoS (for the Cisco
836 and 837 routers)—ATM Traffic Universal Bit Rate
(UBR), Variable Bit Rate non real time (VBRnrt), Variable
Bit Rate real time (VBRrt) and Constant Bit Rate (CBR)
with per-VC Queuing and Traffic Shaping
Provides QoS guarantees for real-time traffic, with ability to send traffic over the
appropriate virtual circuit to provide ATM-level shaping and ensure that no head-
of-line blocking can occur between circuits of different or equal traffic classes
