secure and reliable access to the Internet or corporate ofﬁces.

Benefits of Cisco 827-4V Business-Class ADSL Router

Business Class Security for Internet and VPN Access

To take advantage of unprecedented opportunities offered by Internet-based communications and commerce, private

information must remain secure. Cisco IOS software provides many features to enable network security and the

Cisco 827-4V router offers a stateful inspection ﬁrewall. It denies or permits WAN trafﬁc based on a session’s state,

so requests from users behind the ﬁrewall can be received, while preventing unauthorized access. It also provides

basic security features such as standard and extended access control lists (ACLs); Lock and Key (dynamic ACLs);

router and route authentication, generic routing encapsulation (GRE) tunneling; and Network Address Translation.

These perimeter security features control trafﬁc entry and exit between private networks, intranets, extranets, and

the Internet.

BeyondFirewall security the Cisco 827-4V router alsosupports optionaldata encryption for VirtualPrivateNetworks.

VPNs allow secure communications over a public infrastructure such as the Internet. While a ﬁrewall provides

perimeter network security for a given location, VPNs protect data when sent from one site to another, such as a

branch ofﬁce to corporate headquarters. VPNs use data encryption and secure tunnels to protect the integrity of data

traveling over these public connections. The Cisco 827-4V router supports IPSec 3DES encryption, which provides

the most secure form of data encryption, and prevents hackers from gaining access to corporate information.

To simplify the set up of VPNs at remote locations the Cisco 827-4V router supports Cisco Easy VPN. The Cisco

Easy VPN Remote feature allows a Cisco router with a static or dynamic IP address to automatically establish and

maintain a VPN tunnel to a Cisco Easy VPN Server or concentrator. This allows the same ease of conﬁguration and

ongoing policy management of VPNs that VPN software clients provide. This cost effective solution is ideal for

remote ofﬁces with little IT support, or large CPE deployments where it is impractical to individually conﬁgure
