First check if your ISP blocks port 80. Unless your router is bridged, you need to open up the fire-wall for incoming traffic on port 80. You will most likely find this under "Game & Application Sharing" or "Port Forwarding / Port Triggering" in your router's admin interface. Try forwarding port 80 to your work-station, install node.js and run the HTTP-server-example. Then ask a friend if he/she can connect to your IP via the browser.

When you got port-80 working, you need some hardware: A cheap server and a cable to connect it to the router. An old laptop will do as server (KVM and UPS for free).

You also need to decide what software to run, I would go with Ubuntu server as it's the most friendly. Create a bootable USB-stick.

Setup SSH so that you can access the server from your work-station/laptop.

Signup to a DNS service and point a domain name to your IP.
