asp.net hosting with iis

i made an asp.net website. I can access it on the local network but i cant access outside of it. i have forwarded incoming request from port 80 to my local ip-address and my provider is comcast and i checked thier website and port is not block. In the IIS manager, i set the default website to run on my local-ip adress and port 80. I added exceptions to my firewall for port 80 also. what else do i need to do?

heres how i try to acces开发者_如何学Gos the website from outside the network. I use whatismyip.com to get the external ip address. then i type http://whatismyipaddress/default.aspx. I even tried with different port, nothing work

There are several things to check to make sure they are setup correctly, but my first guess is that you have setup your domain to point to your computer's local ip address behind the router and that it is not an external IP address. Computers that are not in your network don't know how to find your computer even when they have your IP address.

There are detailed instructions on how to do the whole process here: http://lifehacker.com/160945/ask-lifehacker--host-my-web-site-at-home

I believe the missing link for you is to setup something like DynDNS at http://DynDNS.com. Even though it looks like they don't have a free option at first glance, they do.
