Enable force ip with command line option

With the GUI option, I can check a box that says to force the IP. How can I do this same thing with the command line option?
I have read many different forum posts but have not come up with a solution yet.

I know it it not set because here is a snippet from my log file:

[Force IP: No]

Basically, we had to have the GUI instance create a whole new .ini file and then have my .bat file reference that new .ini file. For some reason the FtpForcePasvIp=1 did not work when I put it in a partial .ini file. It does work in the new .ini file that was created.

Now, my force IP says yes and I can transfer my file with the put command. :) :)
