Key Features and Beneﬁts

Multiuser Access

Through Network Address Translation (NAT) the Cisco 806 router allows multiple users to share a single broadband

connection. Additionally, an integrated 4 port Ethernet hub allows up to four PCs or networking devices to be connected

directly to the router.

Business Class Security

To leverage the unprecedented opportunities offered by communications and commerce over the Internet, private information

must remain secure. Cisco Secure Integrated Software provides many technologies to build a custom security solution. The

elements of security services include perimeter security, identity, monitoring, privacy, ﬁrewalls, IPSec encryption, and VPNs.

Standard Security

Perimeter security refers to the control of trafﬁc entry and exit between network boundaries, such as between private

networks, intranets, extranets, or the Internet. Cisco IOS perimeter security technologies provide a highly ﬂexible, superior

solution with features such as:

• Standard and extended ACLs

• Lock and Key (dynamic ACLs)

• Router/route authentication, authorization, and accounting (such as Password Authentication Protocol [PAP]/Challenge

Handshake Authentication Protocol [CHAP])

• Network Address Translation (NAT)

• Token Card authentication with Cisco Secure authentication

• NAT eliminates the need to re-address all hosts with existing private network addresses and hides internal addresses from

public view. For businesses that want to allow selected access to the network, NAT can be conﬁgured to allow only certain

types of data requests such as Web browsing, e-mail, or ﬁle transfers.

Enhanced Security

Dynamic or Stateful Firewall—Companies increasingly rely on internal networks and servers for accessing company data.

To leverage the Internet as a key business tool, companies must connect their internal networks to the Internet while keeping

sensitive internal data secure. Company data can be protected against unauthorized access with stateful ﬁrewalls. The

integrated Cisco IOS Firewall Feature Set is a stateful ﬁrewall that provides:

• Stateful (dynamic) ACLs (application/context based)

• Java blocking

• Denial of service attack detection and prevention

• Real-time alerts and audit trails

• Dynamic ﬁrewalls provide these vital enhanced security features. The term ﬁrewall is used by many vendors but not

uniformly referred to as stateful ﬁrewalls. Firewalls that are not dynamic do not provide these enhanced security features.

• SSH for encrypted administration - Allows the router to be managed remotely with encrypted text for updating or

changing conﬁguration commands

VPN Support

The Cisco 806 provides optional IPSec encryption technology to enable small ofﬁces and telecommuters to utilize VPNs.

IPSec encryption provides privacy, integrity, and authenticity for transmission of sensitive information over the Internet. The

unique end-to-end Cisco offering allows customers to implement IPSec encryption transparently into the network without

affecting individual PCs. The Cisco 806 router supports:

• IPSec tunneling with data encryption standard (DES)
