1. A data processing network comprising:
- at least one server; and
at least one hub connected to said server for allowing at least one client connected to said server, wherein;
said client transmits packets to said hub;
said packets have header information indicating a source and a destination of said packets;
said hub changes said header of said packet such that said packet is directed to said server instead of an original destination; and
said server processes said packet and forwards said packet to said original destination.

Abstract
A method and structure for processing packets of information over a data processing system is disclosed. The packets have header information indicating a source and a destination of the packets. The method includes receiving a packet from a client, forwarding the packet to a hub of a local area network, changing the header of the packet such that the packet is directed to a server instead of an original destination, processing the packet through the server to produce a processed packet, and forwarding the processed packet to the original destination.
