One of the original replies to this thread suggested you try EchoVNC, and maybe that's a better solution for you. Using EchoVNC, you can establish a persistent TCP connection to an echoServer of your choice (ideally, one you control). We run one a demo one at "demo.echovnc.com:443", password "demo2006" if you'd like to try it out. Don't get me wrong: Hamachi is a good solution for establishing firewall-friendly connections across the Internet, for most users. AFIAK, though, it uses a UDP punch-thru technique described here: http://www.brynosaurus.com/pub/net/p2pnat/ As that paper describes, the UDP technique will not work well in environments that (1) restrict outbound data to TCP, (2) utilize a web-proxy, or (3) utilize a NAT'ing router that doesn't work correctly with the Hamachi UDP synchronization. hope that helps, Scott > Here is the reply from Forum.. > >> Hello, >> >> Is it possible to connect two machines or two networks which are >> behind the firewall of ISP and are from different countries? >> Actually, We can surf the webpage only..
