Hi we have made a Karaoke program using Delphi. It allows you to sing karaoke with your friends! We have also made a Multi player version. The multi player version uses Indy components and connects to your friends to sing together.
There is a TCP connection which initiates a file transfer to send the karaoke mp3 file. And the actual audio is sent via UDP. The problem is we are having trouble connecting to users behind NAT devices such as routers.

Introduces STUNT Simple Traversal of UDP Through NATs and TCP too (STUNT), which extends STUN to include TCP functionality, is a lightweight protocol that allows applications running behind a NAT to determine external IP and port-binding properties, packet filtering rules and various timeouts associated with TCP connections through the NAT.
We would like to know if you can help us implement a STUNT server in our program code so people can connect to each other behind NAT. There is an existing STUNT server onsite coded in java and C#. We believe you can use the C# version along with our Delphi code for the purpose of this project.

The other method would be to wrap the udp packets used in audio to a tcp packet and use UPnP to open the ports when needed.
