Abstract: A Network Access Control (NAC) device has at least first and second network interfaces with first and second network addresses, respectively, for providing connection to the network, and a computer device interface for providing connection to a user's computer device. A first network channel is configured in the NAC device over the first network interface for providing transactions between the computer device and the network using first application software installed in the NAC device. A second network channel is configured in the NAC device over the second network interface for providing transactions between the computer device and the network using second application software installed in the computer device.
