UDP Hole Punch - repost

I need a simple code ( or any .net language) that demonstrates how to do UDP hole punching (or TCP nat traversal, even better - OPTIONAL).

I'm looking for someone who knows and has already done this. Bidders MUST show me working example works related to UDP or TCP hole punching.

Please do NOT bid if you have not done this before and do NOT give me open-source/commercial SIP packages or things like that. I only need simple, straight-to-the-point example codes. I do not wish to dissect a huge sip package.

Here is description sample should work.

Client A and client B are behind different NAT.

A & B Connects to server S.

Now A & B should establish connection with each other and communicate without server S.

Thank you and looking forward to your solution.

Skills: .NET, Visual Basic
