Cisco SOHO 71 Broadband Router

Secure, shared Internet access for small offices and home offices with the proven reliability and manageability of Cisco IOS software.

The Cisco SOHO 71 router is an Ethernet to Ethernet router that connects to a DSL or cable modem and allows multiple users to share a broadband connection while offering:

Secure Internet access with manageable stateful firewall

Simple set up

Proven reliability and manageability with IOS software

Every business connected to the Internet should be concerned about security, but simple DSL and cable modems do not provide business class protection. Additionally, modems usually allow only single user access. The Cisco SOHO 71 router, recommended for up to five users, allows all users in a small office to share a secure broadband connection with an integrated stateful inspection firewall. Corporate teleworkers and agents can also take advantage of the Cisco SOHO 71 router when using VPN software clients installed on individual PCs to securely connect back to a corporate network. The Cisco SOHO 71 router adds remotely managed firewall protection that protects both the corporate network and the home office from hackers. For all users, the SOHO 71 router is easy to set up with a web based configuration tool and since it runs Cisco IOS software, business of all sizes can take advantage of its proven reliability and manageability.

Secure Internet Access with Stateful Firewall

The Cisco SOHO 71 Router allows business users to take advantage of a single, affordable, broadband connection with a static or dynamic address for multiuser access (broadband modems provide only single-user access). The Cisco SOHO 71 Router also has a four-port hub for up to four directly connected PCs. An external switch can be added for more than four users.

Broadband DSL and cable connections provide fast access and are always on, so users must ensure that their private business and personal information remains secure. Cisco IOS Software provides many features to enable basic network security features, including access lists for packet filtering, router authentication, and Network Address Translation (NAT). However NAT and simple packet filtering are not enough to provide business-class firewall security. The Cisco SOHO 71 Router provides a built-in Cisco IOS Firewall. This stateful inspection firewall provides more intelligent security by inspecting each packet to determine whether or not entry is permitted. This scenario lets users accomplish their goals, while preventing unauthorized traffic from entering the always-on broadband connection.

Users who need to securely connect to a corporate network over the Internet often require encryption with IPSec for virtual private networks (VPNs). Teleworkers can benefit from the addition of a Cisco SOHO 71 to their home office. Users can use a VPN client on their PC to access the corporate network, and with IPSec pass through supported this connection is seamless to the Cisco SOHO 71 router. When users turn off the VPN client, both the company and the employee benefit from the Cisco IOS Firewall continually protecting the home office. Desired parameters for the Cisco IOS Firewall can be determined and managed remotely by an IT manager or service provider. For customers who prefer the management, visibility, and control of having both the firewall and VPN termination in one device the Cisco 806 Broadband Router can be used. It provides features similar to the Cisco SOHO 71 router with additional firewall features and support for up to ten IP Security Triple Digital Encryption Standard (IPSec 3DES) VPN tunnels terminated on the router itself.

Simple Setup

Easy to Set Up and Deploy with Device Manager and Custom Configuration Service

The Cisco SOHO 71 Router is shipped with a default setup, providing easy installation for many DSL, cable, and Ethernet scenarios. Depending on the broadband service, customized information may be required. Specific information may be entered into the router by using the Cisco Router Web Set Up tool (CRWS). Users may view this device manager from their PC Web browser, choosing a setup template, entering passwords, defining access lists, and enabling the stateful firewall.

Cisco greatly reduces the cost of deployment at no additional cost for customers who must deploy large numbers of devices with custom configurations. The Cisco Configuration Express service applies configuration templates and unique addresses to each router, then ships the router directly to each user/installer. Service providers, system integrators, and enterprises utilize Cisco Configuration Express to eliminate product logistics and warehousing costs.

Proven Reliability and Manageability with Cisco IOS

The Cisco SOHO 71 Router is based on powerful Cisco IOS technology. The Cisco SOHO 71 Router supports centralized administration and management via Simple Network Management Protocol (SNMP) and Telnet, and local management through the router console port.

Cisco IOS Software is run on most of the routers that make up the Internet, and businesses of all sizes can take advantage of the reliability and manageability benefits. Because Cisco IOS Software is widely used for mission-critical enterprise networks, small business and enterprise teleworkers can also depend on Cisco SOHO and 800 Series routers. The following tables (2-5) list key products features and benefits and product specifications.
