WAN Confiuration / Ports

Friends I have an WAN address pointing to a private IP which resolves to an installation of FREEPBX (for web call back). When I attempt to resolve the WAN address it just points to my firewall/router login screen so I don’t have the routing worked out correctly. I would like to know which ports I should be forward from the WAN to the private IP?
