with private network addresses. Unlike a DSL modem, which allows only a single PC to connect to the Internet at a time, the Cisco SOHO 77H ADSL routere allows multiple PCs to connect to the Internet simultaneously. The SOHO 77H router includes an integrated four port Ethernet hub to allow up to four devices to connect directly to the router.

Business Class Security with Stateful Inspection Firewall

With DSL’s always-on connection network security is essential. The Cisco SOHO 77H ADSL router enables service providers to offer true business class security with a stateful inspection firewall that helps protect users from unauthorized access from hackers allowing friendly traffic to pass through while stopping unwanted traffic at the firewall. A stateful firewall 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.

If an intruder attempts to gain access to the network through the SOHO 77H Router and is rejected the firewall tracks the user through an audit trail. This audit trail can then help identify an attack in progress and locate an intruder to prevent future attempts. In addition, the firewall uses NAT to hide internal IP addresses from the outside world to further keep the network secure.

Easy Set Up and Deployment

The Cisco SOHO 77H Router includes the Cisco Router Web Set up tool (CRWS), a web based configuration tool that allows users to quickly self-install the router without knowledge of Cisco IOS software. Because CRWS is web based, no additional software needs to be installed on a user’s PC. They simply point a browser to the router and follow a few simple sets to quickly get the router up and running.
