HTTPS/SSL connection problem

[FrozenState]

When I connect to my website using http://localhost or https://localhost, it works and I get presented with the xampp screen, however when I try to connect using a dns hostname like dyndns, it work connects for both http://xxxxxxxx.dyndns.org and https://xxxxxxxx.dyndns.org, however when I try to connect to https://xxxxxxxxx.dyndns.org, it presents me with the router login screen. All my configurations for xampp are default with installation. Sorry if this is a noob question, I'm still trying to learn how all of this functions Any help will be greatly appreciated!

Make sure you are port forwarding the server ports 80 (HTTP), 443 (SSL) and 3306 (MySQL) which XAMPP uses.
