I have installed IIS. I have browsed to my website on IIS using the 'Browse *:80 (http)' link in IIS. This navigates to http://localhost. That link is only going to work on my own machine.
I don't care about my IP address changing (I'm going to show my website for a few hours max every now and then so can update it and resend the link as and when required).
How do I make my website accessible to the internet? What url should I use http://82.11.220.212 (where 82.11.220.212 is the IP of my computer)? Do I need to disable firewalls / add exceptions to my modem / router?
