Domain mapping setup and errors

I'm trying to setup domain mapping with enom.

I already have a reseller account. I've already setup the IP request and have added my proper user and password info.

Here is the error I get at the moment.

User not permitted from this IP address - 4

Are there any additional steps to follow/settings. I've tried enable ssl because I have certificate and also tried disable.

Any help would be greatly appreciated.

Thank you
Billy
