Force Application to Use Specific Network Card

Routing Specific Applications Through a 3G Connection
It's a common scenario: you're connected to a network, and you also have a 3G card installed. You might want to direct the internet traffic of only specific applications through the 3G connection, while others continue to use the primary network.
Achieving Selective Application Routing
This is indeed possible, and the following information details how to accomplish this configuration. The process allows for granular control over which programs utilize the 3G connection.
Essentially, you can isolate the internet access for particular software, ensuring that only designated applications are routed through your 3G connection.
Benefits of This Configuration
- Cost Control: Limit data usage on your 3G connection, avoiding unexpected charges.
- Performance Optimization: Route bandwidth-intensive applications through the faster 3G connection.
- Security Enhancement: Isolate sensitive applications for increased security.
By implementing this method, users gain a significant degree of flexibility and control over their network connectivity.
This technique provides a practical solution for managing data usage and optimizing performance in situations where both a primary network and a 3G connection are available.
Installing ForceBindIP
Begin by navigating to the ForceBindIP download page and obtaining the zipped archive.

After the download completes, extract the files contained within the zip archive.

It is necessary to copy both of the extracted files.

Subsequently, paste these files into the following directory:
C:\Windows\System32

To open the command prompt, simultaneously press the Win + R keys, type cmd into the run dialog, and then press enter.

Once the command prompt is active, execute the following command:
cd C:\Windows\System32

To associate an application with a specific network adapter, utilize the following syntax:
ForceBindIP %NetworkCardsIP% %PathToProgram%
As an illustration:
ForceBindIP 127.0.0.1 “C:\Program Files (x86)\Mozilla Firefox\firefox.exe”
This example is based on the following assumptions:
- The desired network card possesses an IP address of 127.0.0.1.
- The application to be bound is Mozilla Firefox.

Keep these points in mind:
- Always provide the complete file path to the application.
- Enclose the path in quotation marks if it contains spaces.
- The application must be launched using this method each time you wish to bind it to the specified network card.
This completes the installation process.
