How to Force an Application to Use a Specific Network Card

Have you ever been connected to a network, and plugged in a 3G card and wished you could make only a certain program use your 3G connection ? Well you can, read on to find out how.

Installing ForceBindIP

Head over to the ForceBindIP download page, and grab a copy of the zipped version.

Once it has downloaded, extract the contents of the zip file.

You will need to copy both files.

Then paste them in:

C:\Windows\System32

Now press the Win + R keyboard combination and type cmd into the run box, then press enter.

When the command prompt opens, run the following:

cd C:\Windows\System32

Now we can bind an application to a network adapter, to do this type:

ForceBindIP %NetworkCardsIP% %PathToProgram%

For example:

ForceBindIP 127.0.0.1 “C:\Program Files (x86)\Mozilla Firefox\firefox.exe”

This assumes:

• The network card you want to bind the application to has an IP of 127.0.0.1
• The program you want to bind to that network card is Firefox.

Just a few things to remember:

• You have to give the full path to your program.
• If the path contains spaces, enclose it in quotes.
• You will have to launch the program via this method every time you want to bind it to that network card.

That’s all there is to it.
