How to port forward using Dlink DI-524 for Emule?

DMZ is a feature that is included on some routers but is not in Internet sharing software. A DMZ allows a single computer on your LAN to expose ALL of its ports to the Internet. When doing this, the exposed computer is no longer ?behind? the firewall.

Port Forwarding vs DMZ
A DMZ is far easier to set up than port forwarding but exposes your entire computer to the Internet. Sometimes TCP/IP applications require very specialized IP configurations that are difficult to set up or are not supported by your router. In this case, placing your computer in the DMZ is the only way to get the application working. Placing a computer in the DMZ should be considered ?temporary? because your firewall is no longer able to provide any security to it.

Try updating the firmware of your router.
