***** There seems to be a bit of confusion. I probably should not have used the terminology 'port forward'. I do not want the clients to have to make any configuration changes in order to route from the private network to the public network. I would like the application to work similar to the [login to view URL] application however much simpler. Another example would be a broadband router. You set the client's gateway address to the 'local private ip' of the machine running this software and the software will perform some level of network address translation to route the client's packets (I only care about port 80, 25, 110) to the internet and vise versa.) ***** I need a small application that basically does port forwarding or network address translation. I only need port 80, 25, 110 to forward. I would basically like to be able to disable or enable a specific IP address from forwarding packets. The code would work like an internet cafe gateway/server. There is a Raw socket class for .net available at: [login to view URL] That code captures packets, if you modify that to forward the packets you have a head start. You can write the code in anything you want as long as it is a mainstream language (c, c++, java, c#, vb.net, vb). The application must run on Windows XP.
