You tell us that your server is not in public zone. But when you say to use port forward, DMZ and DDNS we are convicted that YES, the server is on a DMZ Zone, opened to the Internet access. http is port 80 tcp (DDNS), and the worst if you setup your IP Address server in the DMZ config space at your Router, you definitely put your server on the internet border. Just my tip!
