Hi,
I am currently setting a tracker site, and when I try to change the url to my external ip address instead of localhost, but it doesn't work. Then I went to check my ports and I realized that my port 80 is closed.
So I have logged in to the router configuration site and configured it under the virtual server.
The configuration is as below:

After I configured, I still can't acces via the external ip, and the port 80 is still closed.
Hope that you guys may help me in this problem.
Thanks.
