Client/Server Tunnel/Proxy, Like OnSpeed


Unfortunately, the previous freelancer who i awarded the project to, did not respond to my emails anymore.

I need a client/server proxy software for web surfing in C# or whatever you think does it better.., i'll list some features i need and can also provide sample applications if needed.

1) Client should support Win XP, Vista 7 and 8.., i may need MAC/iOS and Linux at a later time.., The server side application can be Win or Linux based.

2) It has to support at least 100 clients with 50 concurrent connections per client (will be 5000 con-current connections).

3) An encryption methods (URL's need to be encrypted too.)

4) It has to support Authentication (Auth with a radius server is preferred).

5) Supporting compression is preferred (ie. using zlib library).

Please do let me know if you have a question.

Thank you,
