Whitelist IP addresses with split_traffic

Hi,

I have an issue with a/b testing setup. I'm splitting traffic based on $remote_addr and setting up a cookie to ensure the user is always going to the site it was chosen for him.

My problem is that I want clients coming from certain IP addresses to go to a certain version of the site, but it doesn't seem to work as expected. I have attached the configuration files for reference.

Is there a way I can achieve this?

Thanks.
