Forms API does not update the correct User IP Address

Hi,
I looked at Form API only allows subnetwork IPs
before posting again. The above link did not help me. I am using the Forms submission API to create new contacts. However, I noticed that the client Ip Address is not being set to the one I am passing, rather is seems to be my ISP provider IP
Given below is the details of my API call. I am using Fiddler to make the call.
