I believe my connection is a static IP as I have checked it several times and the IP number has stayed the same from the WAN point of view.
That isn't an indication that you have a static IP. That only tells you that your IP hasn't changed recently.
You will know you have a static IP if your ISP told you your IP address, netmask and default gateway. If you have a username/password, you don't have a static IP address. If you use DHCP, you don't have a static IP address.
