DATA SHEET

CISCO 830 SERIES SECURE BROADBAND ROUTERS

Advanced security for data, voice, and video access ideal for small oﬃces and teleworkers.

The Cisco® 830 Series of secure broadband routers is ideal for providing secure Internet and corporate network connectivity to small remote oﬀices

and to teleworkers. Cisco 830 Series routers provide a wide range of integrated security services and advanced quality of service (QoS) features for

high-quality data, voice, and video applications. They oﬀer easy deployment and remote management features with Cisco IOS® Software.

Figure 1. The Cisco 830 Series Router

The Cisco 830 Series is comprised of the Cisco 831 Ethernet Broadband Router, the Cisco 836 ADSL over ISDN Broadband Router with an ISDN

BRI port, and the Cisco 837 ADSL Broadband Router. The Cisco 831 router has an Ethernet WAN port for use with an external digital subscriber

line (DSL) or cable modem. The Cisco 836 router supports asymmetric DSL (ADSL) over Integrated Services Digital Network (ISDN). The Cisco

837 router supports ADSL over POTS (basic telephone service). All models oﬀer a four-port 10/100 Ethernet LAN switch for connecting multiple

PCs or network devices in a small-oﬀice network.

ADVANCED SECURITY AND PERFORMANCE FOR ENTERPRISE-CLASS VPNs

The Cisco 830 Series delivers integrated enterprise-class security services, including hardware-accelerated IP Security (IPSec), Triple Data

Encryption Standard (3DES) encryption for virtual private networks (VPNs), and stateful-inspection ﬁrewall for secure Internet connectivity.

Optional advanced features—such as OSPF, RIP, and RIP v2, EIGRP and BGP (limited) routing protocols; Cisco Easy VPN Remote (a software

feature that allows simple deployment and management of VPNs) and Easy VPN Server (limited to ﬁve users); public key infrastructure (PKI)

security requiring digital certiﬁcates; IPSec Network Address Translation transparency (NAT-T); the Cisco Intrusion Detection System (IDS);

WCCP and URL ﬁltering—help ensure that the small oﬀice receives the highest level of security, which contributes to the corporate network’s

security.

HIGH-QUALITY, SECURE VOICE AND VIDEO

The advanced QoS and high-performance encryption features oﬀered in Cisco 830 Series routers provide high-quality voice and video services to

remote users. When IP phones are connected at a remote site, a Cisco 830 Series router can queue and prioritize the voice traﬀic over data traﬀic to

ensure a high-quality, secure voice-over-IP (VoIP) connection from the remote or home oﬀice back to the corporate network.

MANAGEABLE, SCALABLE, AND RELIABLE ACCESS

The Cisco 830 Series uses valuable management and deployment tools to deliver the industry’s lowest total cost of ownership for connecting small

remote oﬀices and teleworkers to the corporate network. As a remotely manageable platform, the Cisco 830 Series supports advanced remote

troubleshooting commands available in Cisco IOS Software; a virtual auxiliary (AUX) port for out-of-band management with an external modem

or through an integrated ISDN Basic Rate Interface (BRI) ISDN port (Cisco 836 router); and Secure Shell (SSH) Protocol for secure in-band

management via Telnet. Cisco 830 series routers come equipped with two embedded remote management tools, Cisco Security Device Manager

(SDM) and Cisco Router Web SetUp Tool (CRWS).

For scalability in deployment and management, the Cisco Router Web SetUp Tool, available in several languages, allows nontechnical users to

quickly set up the router and turn on key features such as the stateful ﬁrewall. Cisco Security Device Manager provides added functionality for

Web-based security and router set up and monitoring. Cisco provides a suite of solutions—such as Cisco Easy VPN, the Cisco IE 2100 Intelligence

Engine, Cisco VPN Solution Center (VPNSC), the CiscoWorks Router Management Center (Router MC) and Cisco Conﬁguration Express—that

allow for scalable network deployment and management, including automated security policy push and conﬁguration updates.

For reliable access, the virtual AUX port on Cisco 831, 836, and 837 routers can be used for dial backup with an external modem, should the primary

WAN connection fail. On the Cisco 836 router, an integrated ISDN BRI S/T port also provides ISDN dial backup and out-of-band management. The

Cisco 830 Series runs Cisco IOS Software, the industry-proven software that has become the standard for reliable business access.

FEATURES AND BENEFITS

Table 1. Key Product Features and Beneﬁts

Features Beneﬁts

Advanced Security and Performance for Enterprise-Class VPNs

Demilitarized Zone Port (DMZ) One of the switch ports could be convertsed in to a DMZ port to place publicly

accessible servers or to segregate users on the LAN.

Dynamic DNS The router could be accessed by a DNS name. Hence the router will be accessible

even if the WAN IP address keeps on changing.

Stateful-Inspection Firewall Oﬀers internal users secure, per-application dynamic access control (stateful •

inspection) for all traﬀic across perimeters

• Defends and protects router resources against denial-of-service (DoS) attacks

• Provides context-based access control (CBAC)

• Checks packet headers and drops suspicious packets

• Protects against unidentiﬁed, malicious Java applets

• Details transactions for reporting on a per-application, per-feature basis

Network Security Features with Cisco IOS Software,

Including Access Control Lists (ACLs), Network Address

Translation/Port Address Translation (NAT/PAT), Lock &

Key Security, Dynamic ACLs, and Router and Route

Authentication

Provides perimeter network security to prevent unauthorized network access

Cisco IDS Detects and prevents DoS attacks and unauthorized network access; sends alerts

to initiate appropriate action
