Hi Freelancers! Please, read all the information / requirements before place a bid. I already created a remote desktop application, using Delphi 7 and Synapse ([login to view URL]), that allow users to see/control a remote computer and transfer files/folders, but it works only on local network area (LAN). Now is been necessary it to work over internet (WAN), behind routers, just like "TeamViewer" does... I need you to create an example code / application, that can send a simple stream (file) from a computer to another, each one in different LAN areas (behind routers), over the internet, without the need to configure port forwarding, etc. In my researchs, I understood that there is more than one way for doing this job. I expect it to be done in the most efficient way, in order to not compromise much the transmission speed. I can buy some Delphi third party component / SDK licence to make things easier for you. For now, I prefer to use Synapse UDP protocol and Delphi 7. But if you already have something done with a different protocol or Delphi version, please let me know (I have Delphi XE4 and below licences). Please, see attached an ilustrating image. I need PC-01 to connect with PC-02 (same LAN) or PC-01 to connect with PC-03 (outside LAN). Thank you for your interest in this job!

I propose making a binding to PJNATH or other library implementing ICE. This way you will use tested C++ library in your Delphi application, have ability to use both STUN and TURN whatever is better in each case. Using RFC protocols enables potential further enhancements such as WebRTC; and server infrastructure (STUN servers, TURN servers) already exists, with several replaceable implementations available. I have previously done bindings for smaller libraries like libyaml.

Hello, im very well experienced delphi coder, my work is mainly about windows api, security, encryption etc. Im also well known in malware coding scene, so basicly this what you ask is not too hard, there are few approaches that this could be done, so if you like we could discuss it. I use delphi and ASM, but for your needs, we can use any delphi you like, that being said, i prefer not to use synapse or any other 3rd party rtl's but i write modules as i need them. That would be all. If interested, leave me a message. Thanks.
