US Patent 8363658 Dynamic firewall and dynamic host configuration protocol configuration

A system is provided comprising a computer system, a configuration database, and a dynamic network interfaces application that receives a message from a network access component containing a request to authenticate a client device accessing a network service, determines that a policy requires the client device to be associated with a virtual local area network to access the network service, and authenticates the client device for association with the virtual local area network. The dynamic network interfaces application also searches the configuration database for configuration information to provision the virtual local area network, assigns the configuration information to the client device, the network access component, and a firewall component, and sends a reply containing the configuration information to the network access component and the firewall component in response to the request, wherein the configuration information comprises settings to provision the virtual local area network.
