I am working with a client who is using First Data Global gateway for their payment processor. I use PHP and curl to post payments. The problem I am running into is that the payment processor requires port 1129 to be open and a .pem. Since the client is with yahoo business web hosting I cannot get them top open port 1129. (I assume I would need a dedicated IP for this?)
Have any of you used a hosting provider with First Data Global Gateway (linkpoint)? The port option is a requirement.
