Why are you unable to connect to the intranet site from the client? Because Intranet is on port 4444 so we would have to open up that port Lab Challenge
Creating Windows Firewall Rules
Overview
The port you opened in Exercise 12.3 enables clients to access the default website hosted by your web server, but not the Intranet website.
In this challenge, you must configure your web server to allow traffic to the Intranet website.
Mindset
Windows 8 often provides more than one way to complete a given task.
The Windows Firewall control panel provides a relatively simple interface to the firewall, but it is not a comprehensive one, as we saw in the previous Exercise.
Completion time
