Do you realize that this is the Quick Answers section? What you are asking can be a bit too wide to be explained here.

I would recommend you to search for information in google, start trying and when you face problems you don't know how to solve, then come back and ask concrete things. You will get faster and better help that way.

If you're a beginner at coding, this is WAY too far over your head to write.

You're not going to write the bulk of this application in C# or VB.NET. This may require writing a network stack driver in C/C++ depending on your setup.

But, you will have to write a TCP/IP server, that supports various protocols specific to firewalls and proxy servers. If you don't have a deep understanding on how TCP/IP works, there's your starting point. Start doing research.
