Man - thanks so much for all the answers so quickly. Without going into boring detail....I have a client that has a patent on a network security device that he now wants me to build a prototype for. Part of the patent states that the device is 'invisible' to the Internet because it has no configured IP ports. It is supposed to sit INLINE in the network somewhere (say between router and single PC) and filter/block packets that come through it to the destination PC or vica-versa. It's kinda like a bridge (only with logic processing during the bridge operation). If we address the ports, then I depart from the patent and I have no idea what is allowed from a legal standpoint in doing something like this. As a high level application programmer (mostly Java for the past 15 years), I find myself woefully short on the knowledge/experience to accomplish such a task.
But again - thanks all for the responses!
