Client Has a Problem With the Shared IP Address

My client cannot access their site from their location (it works everywhere else). Their IT support person cannot create a forward to the IP address the site is pointed to.

Is there a way to get a static IP address instead of a shared? Or does anyone have any other suggestions?
