NATural IP allows you to run peer-to-peer and streaming media applications from behind a NAT firewall, securely and easily, even when your whole network is sharing one external IP address. NATural IP is simple to use, and works with most existing and future Internet based applications, such as video conferencing (e.g. NetMeeting), instant messaging (e.g. ICQ, AIM), file sharing (eg BadBlue, KaZaA), etc. NATural IP does not require you to open your firewall or reduce your network security in any other way.
