To build it you need to have Visual Studio 2019+, Windows Driver Kit (WDK), Golang 1.18+

There's now a build.bat script in the splitter-control directory. Use it to build the control programm

@shaiful73 that means you didn't build and install the driver

[shaiful73]

I have followed Step 1, 2, and 3 of this doc: this: https://learn.microsoft.com/en-us/windows-hardware/drivers/download-the-wdk
Installed Visual Studio 2022, SDK, WDK.

Then opened splitter.sln with Visual Studio 2022.
Then tried to build by Ctrl+Shift+B. Then got arround 16 errors. I have attached screenshoots of errors.

Yes, there're some compatibility issues with some SDKs.
I will address it.

@Zensey thanks brother. I will wait for you.

@shaiful73
Done. It was a configuration problem, the 'KERNEL' env. variable was missing in a few configurations.
Please update and try to build.

1. After building the project, I obtained three files related to the splitter: .cat, .inf, and .sys.
2. I successfully installed the driver by right-clicking on the .inf file and selecting "Install."
3. When running splitter-control.exe from the command line, I encountered the following error:
   C:\Developer\split-tunnel\splitter-control>splitter-control.exe
   17 0.0.0.0/0 192.168.20.1
   3 17 192.168.20.131
   redirectIP: 192.168.20.131
   \.\Splitter
   err# The system cannot find the file specified.
   Press the Enter Key to stop anytime

Note: Screenshots of the driver installation and related files are attached.


Please help me identify which part I might be missing?

By the way this driver doesn't handle UDP in an optimal way, so there's a place for optimisation.
If things like that are interesting to you and you'd like to contribute, I can make up a plan.

@Zensey, thank you so much for your incredible help with the project—it's working perfectly now! I’m really eager to contribute further, especially to optimizing the driver’s handling of UDP. Please let me know the plan, and I’d be thrilled to dive in and assist however I can!.
