1. A network arrangement comprising:
- an internal network;
a network client coupled to the internal network;
a network attached device (NAD) server coupled to the internal network; and
a NAD coupled to the NAD server in such a manner that the NAD server controls access to and from the NAD;
the NAD server configured to receive from the network client over the internal network a request contained in a data packet for network access to the NAD and to filter the data packet to determine, based at least on an IP address in a header of the data packet, whether the received request for network access to the NAD should be authorized, the NAD server further configured to process the data packet for communication with the NAD and to provide the network client with access to the NAD upon determining that the request for access is authorized, and to deny access to the NAD otherwise.

Abstract
Dedicated firewall security for a network attached device (NAD) is provided by a firewall management system integrated directly into the NAD or into a NAD server. A local area network arrangement includes a network client and the NAD and the firewall management system includes computer readable medium having computer-executable instructions that perform the steps of receiving a request for network access to the NAD from the network client, determining whether the request for network access to the NAD is authorized, and only if the request for network access is authorized, providing the network client with network access to the NAD.

10. A method, comprising:
-
processing, by a network attached device (NAD) server coupled to an internal network, a request for network access to a NAD device, the NAD device coupled to the NAD server and configured to receive communication from an internal network only by way of the NAD server, the request for network access including a data packet that includes at least an IP header, the NAD server comprising a NAD server firewall; determining, by the NAD server firewall, whether the request for network access to the NAD should be authorized or denied based on a filtering of at least the IP header of the data packet of the received request for network access to the NAD; processing, by the NAD server, the data packet for communication with the NAD and enabling access to the NAD upon determining that the requested network access to the NAD should be authorized, and blocking, by the NAD server, access to the NAD upon determining that the request for network access to the NAD should be denied. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A non-transitory computer-readable storage medium having stored thereon instructions that upon execution by a computing device, cause the acts comprising:
-
processing, by a network attached device (NAD) server, a request for network access to a NAD device, the NAD device coupled to the NAD server by way of an interface such that all requests for access to the NAD device are processed by the NAD server, the request for network access including a data packet that includes at least an IP header; filtering of at least the IP header of the data packet of the received request for network access to the NAD; authorizing, by the NAD server firewall, the request for network access to the NAD based on information in the IP header indicating the source and destination of the data packet; processing the data packet for communication with the NAD and enabling access to the NAD upon authorization of the requested network access to the NAD, and blocking access to the NAD of request for network access to the NAD that are not authorized. - View Dependent Claims (18, 19, 20, 21, 22)
