I have programmed a very simple vb .net client/server application which uses the standard .net tcpip sockets classes. On the server application I basically listen on a particular port and the client application communicates to that port on the server application. All is well unless the server and/or the client is behind a firewall or has to use a Proxy server to get out to the Internet. Can someone please explain to me how to go about doing this? I think I need to use http tunneling but don't know if there is some time of .net class or third party something I can use. Any assistance would be greatly appreciated.

If the proxy is a SOCKS proxy, you can use our ProxySocket class [http://www.mentalis.org/soft/class.qpx?id=9].
