1. A system comprising:
- a router, including;
a first interface to communicate with a local area network connection at an end user computer;
a second interface to communicate with a wide area network connection to at a distributed computer network;
detection logic responsive to the first interface, the detection logic to detect user inactivity at the end-user computer; and
blocking logic responsive to the detection logic, the blocking logic to selectively initiate a blocking signal to disable communications received at the second interface from being sent over the first interface to the end-user computer;
whereinthe detection logic and the blocking logic are embedded within an auto-sensing Ethernet port of the router.

Abstract
A system and method for detecting an idle or inactive data port connection on a personal computer (PC) and blocking external access, e.g., Wide Area Network (WAN) access to an end-user PC is presented. The system provides for added security for unattended PCs having broadband connections. The idle time period for detection/blocking logic initiation of a blocking signal to disable communications, e.g., Ethernet port access to the PC, may be for a fixed time period or may be determined by a user of the end-user PC.

9. A method comprising:
-
establishing a broadband connection at routing equipment, the broadband connection including a first local data correction between an end-user computer and the routing equipment and a second wide area network data connection between the routing equipment and an internet service provider; detecting at the routing equipment that the end-user computer has been idle for an idle time greater than an idle time inactivity threshold and determining an inactivity event at the routing equipment; and initiating a blocking signal at the routing equipment to establish a blocking condition, the blocking signal blocking data received at the routing equipment via the second wide area network data connection from being communicated from the routing equipment to the end-user computer via the first local data connection;
whereindetection logic and blocking logic are embedded within an auto-sensing Ethernet port of the routing equipment. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method of routing data at digital subscriber line routing equipment, the method comprising:
-
establishing a first portion of a digital subscriber line connection at digital subscriber line routing equipment, the first portion of the digital subscriber line connection including a local Ethernet data connection between an end-user computer and the digital subscriber line routing equipment, the first port of the digital subscriber line connection terminating at a first port of the digital subscriber line routing equipment; establishing a second portion of the digital subscriber line connection, the second portion of the digital subscriber line connection including a wide area data connection between the digital subscriber line routing equipment and internet service provider equipment, the second portion of the digital subscriber line connection terminating at a second port of the digital subscriber line routing equipment; detecting at the first port of the digital subscriber line routing equipment an indication that the end-user computer has been idle for an idle time greater than an idle time inactivity threshold; and during a first period of time, initiating a blocking signal at the digital subscriber line routing equipment, the blocking signal blocking data received from the second port of the digital subscriber line routing equipment from being communicated by the first port of the digital subscriber line routing equipment;
whereindetection logic and blocking logic are embedded within an auto-sensing Ethernet port of the digital subscribe line routing eguipment. - View Dependent Claims (19, 20, 21)
