D-Link DIR-601 :: Configure Router To Make Website Accessible From The Internet?

I have IIS running in a machine inside my network and I would like to make is visible to the world wide web.To do that, I created a website in the port 8787, which is accessible when the user types 192.168.0.126:8787 in the browser. Of course it works only when the user is inside my network.(IIS running over windows server 2008 OS)Now I want to make it visible to the WWW, so I created a rule to make a port forwarding to it:I went to: Advanced > Virtual Servers and created a rule with the given information:

enabled
Name: website
private ip: 192.168.0.126
protocol: both
private port: 8787
public port: 8787
Schedule: always

This rule created automatically a firewall rule

Enabled
Alow
Source: WAN *
Destination: LAN 192.168.0.126 Protocol: * Port range:8787
always

Unfortunately it isn't enough, if I type myPublicIp:8787  I can't access the website because I either get "connection reset" error or a timeout.I pluged my computer directly in my modem and it worked perfectly.To make a test, I tried to enable the router remote administration on the port 10001. It didn't work.ps: my wireless router is a dlink di-524, I am writing this in this forum because I couldn't find the one related to my router...
