Abstract
A security system for connecting a first computer network to a second computer network is provided. The security device has a pair of computer motherboards, each of which has a network interface adapter for receiving and transferring communications from a computer network to a transfer adapter to be transmitted to the other computer network through a transfer adapter and network interface adapter provided on the other computer motherboard. Each motherboard provides protocol translation from a first protocol to a second protocol and removes source and destination address information from communications transferred to the other computer motherboard. Application program interface shim software or dynamic link library software provides control of communications between the two motherboards for passing code necessary to request and receive services from the other computer network.
