Systems and methods for providing dynamic network authorization, authentication and accounting

A system for transmitting alternate content to a user device attempting to communicate through a network, comprising:

• a network access management system including at least one processor and at least one communications port configured to communicate on a network;
• the network access management system configured to send connection handshake completion data to a user device in response to a connection request from the user device directed to a first device that is external to the network access management system, the connection handshake completion data configured to appear to be from the first device, wherein the network access management system need not communicate with the first device;
• the network access management system further configured to process an incoming request for access to the first device;
• the network access management system further including a redirection data generation module configured to generate response data customized for the incoming request for access to the first device, the response data including alternate content different from content requested by the incoming request;
• the redirection data generation module configured to generate the response data to appear to be from the first device, wherein the response data appears to be from the first device at least in part by including a source address corresponding to the first device in a header of the response data;
• and
• the network access management system further configured to send a response to the incoming request for access to the first device, the response comprising the generated response data.

A network management system, configured to cause a user device to receive alternate content different from what was requested by the user device, the user device being connected to the network management system, the system comprising:

• a communications port configured to receive incoming data from the user device relating to accessing a first network location external to the network management system;
• and
• a processor configured to complete a connection handshake with the user device while appearing to be the first network location, the connection handshake being completed in response to the incoming data and without the need to communicate with the first network location;
• the processor further configured to generate response data customized for the user device, the response data including alternate content different from content to be accessed at the first network location, wherein the response data is customized for the user device at least in part by appearing to be from the first network location, wherein the response data appears to be from the first network location at least in part by including a source address corresponding to the first network location in a header of the response data;
• the processor further configured to send to the user device the generated response data including the alternate content.
