Cisco 828 G.SHDSL

To take advantage of the unprecedented opportunities offered by communications and commerce over the Internet, private information must remain secure. With Cisco IOS Software, the Cisco 828 Router provides basic network security features such as standard and extended access control lists (ACLs), generic routing encapsulation (GRE) tunneling, and Network Address Translation (NAT), which hides private IP addresses behind a single public IP address.

With the always-on connection that DSL provides, it is essential to provide perimeter security with a firewall. Beyond simple packet filtering, the Cisco 828 Router provides a stateful inspection firewall with the Cisco IOS Firewall Feature Set. A stateful inspection or dynamic firewall provides a greater level of security intelligence by allowing or preventing network access based on a session's state. The firewall will allow traffic to pass when requested by a user behind the firewall but will prevent unauthorized network access.

Additionally, when using a public network such as the Internet to connect remote offices and teleworkers, additional security measures must be taken to make those connections secure for business communications. Virtual private networks (VPNs) use security encryption and tunneling technology to make connections over a public network secure. The Cisco 828 Router supports VPNs with the strongest form of encryption, 3DES IPSec, to allow businesses to save money by using low-cost connections to the Internet without sacrificing the security that private leased lines provide. Furthermore, firewall and VPN features enable service providers and resellers to offer revenue-generating value-added services beyond simple Internet access.

The Cisco 828 Router supports the Cisco Easy VPN Remote feature which allows Cisco 800 Series routers to act as remote VPN clients. As such, these devices can receive predefined security policies from the headquarters' head-end, thus minimizing the VPN configuration required at the remote location. This cost effective solution is ideal for remote offices with little IT support, or large CPE deployments where it is impractical to individually configure multiple remote devices. For those at remote offices, the Cisco Easy VPN Remote feature can be configured with the Cisco Router Web Set Up tool (CRWS) Web-based GUI. This makes VPN configuration as easy as entering a password, increasing productivity and lowering costs as the need for local IT support is minimized.

The Cisco 828 Router also supports the Cisco Easy VPN Server feature in Cisco IOS Release 12.2(8)T, or later releases. This allows a Cisco 800 Series router to act as a VPN head-end device in site-to-site VPNs where the remote office routers are using the Easy VPN Remote feature. Policies can then be pushed down to the remote office routers. In addition to terminating site-to-site VPNs, a Cisco 800 running Cisco Easy VPN Server can terminate VPN tunnels initiated by mobile remote workers running VPN client software on PCs. This flexibility makes it possible for mobile and remote workers, such as sales people on the road, to access their headquarters' intranet where critical data and applications exist.

The Cisco 828 Router enables service providers to increase revenue by building differentiated service options based on premium, standard, or best-effort service classes.

It employs quality-of-service (QoS) features such as application-aware networking with IP QoS features and traffic management with ATM QoS features. This enables the router to expedite the handling of mission-critical or delay-sensitive applications, such as enterprise resource planning (ERP) or videoconferencing, while sharing network resources with lower-priority applications such as Web surfing.

By providing QoS features at the edge of the network, applications such as video or IP telephony can more efficiently use network bandwidth, and users of mission-critical applications in remote locations can gain the benefits of traffic management.
