WNDR4500 Ports won't open

Hi,

I am trying to host a Minecraft server via portforwarding, but the router won't let me. I can join the server with my internal IP (IPv4) address, but not via the public IP. I've opened the 25565 port on the router, and checked via http://www.yougetsignal.com/tools/open-ports/ whether the port is opened or not, but the site says it is closed.

Also if I host the server at my parents with a D-Link router, it works perfectly.

What can I possibly do wrong?

If the modem is actually a gateway, then it is blocking the port. What is the manufacturer and model number?

What is between the router and the ISP? Is it possible that there is a gateway in front of the router instead of a modem?
