So your ISP has decided to block port 80?
So your ISP has decided to block port 80, eh? No big deal. You can still serve your website without them knowing!
Step 1: Change the port your webserver runs on.
Here is how you do it. First, you will need to change the port that your web server runs on. I decided to use port 8080. In Microsoft's IIS, you do this by editing the default web site's properties. Right click on the default web site and select Properties. Once you have done that it will bring up another window. Enter your port here. (Note: this tip can be used with other web servers, just figure out how to change the port and continue with step 2.)

Step 2: Create your port 80 redirect.
If you already have a host created that you'd like to use, select modify from the Hosts/Redirects menu. If not click add from the Hosts/Redirects menu. Once you are on the host editing page, select the option "Port 80 Redirect".

After you have done this, enter the IP address of the webserver and the port you selected it to run on. Now click add or modify.
Step 3: Making it dynamic.
If the IP that your webserver runs on is dynamic, you'll want to make sure you are running our dynamic update client, which is available from the downloads page. After you have installed and configured the update client make sure the host you have created or modified in this tip has been selected to be updated.
