I need a solution in delphi native source code to realize UDP hole punching.
Third party components can be used (Fastnet, Indy, ICS or any other freeware components). The solution must run under Delphi 5.
The solution must meet those needs:
Connect any 2 PC's via Internet and exchange each 2 seconds some status informations between the
peers (traffic 10 bytes each 2 seconds)
