But it does have a virtual server option that allows me to forward the port externally.

Whatever the case may be, make sure your port appears as open to an external tool like the one I gave you. There is no point in checking code until you can confirm the port is visibly open the outside.
Hmm... I've tried forwarding it to my internal and external IP addresses and it still says the port is closed. Just to test it, I tried the test tool with port 80 and it still said the port is closed...
