Hosting a Server on the Internet

using resources from www.AskMisterWizard.com

If your home or small office is accessing the Internet like most others, then you've probably purchased DSL or Cable Modem service from your Internet Service Provider, and the Internet address that is assigned to your NAT router will probably change from time to time. Usually this will happen after a few hours of inactivity.

In fact, your own computers are probably assigned a dynamic IP address on your own private network, that will also change from time to time. Most of your computers won't be aware of this, and won't be bothered by it. That's because most of the Internet-related activity that's important to typical users consists of relatively simple applications that have come to be known as "client" processes.

However, as you gain more experience, you may want to host one or more "server" processes. Server processes include:

If your setup is typical, you will have best success if you take 3 specific steps to overcome 3 problems for each server. They are:

Step 1 of 3: The computer or appliance hosting each server will work best if it is allocated a static, unchanging IP address on your local network, so that your NAT router and the other computers on your network can easily find and access the service.

Step 2 of 3: You will need to tell your NAT router how to handle unsophisticated messages destined for the server, and

Step 3 of 3: You will need to inform the people that want to use the service of the public IP address assigned to your router.

Other AskMisterWizard.com movies have dealt with these 3 problems.

If you have trouble with the first of these 3 problems (Configuring a static IP Address for your server host on your LAN), see THIS MOVIE on static IP addressing.

If you have trouble with the second of these 3 problems (Configuring your NAT router to "forward" unsolicited, incoming activity on appropriate "ports", see THIS MOVIE on Port Forwarding.

If you have trouble with the third of these 3 problems (Advertising the IP address of your router so that interested people can use your service), see THIS MOVIE on Dynamic DNS (DDNS).

We are going to assume that your network configuration is typical, and that your NAT router is using the dynamic Internet address assigned by your Internet Service Provider (ISP). If you aren't familiar with NAT routers and the way they share a single Internet Address with multiple PCs on your LAN, then you should watch these 2 movies:

All together, these video resources from AskMisterWizard.com can make it easy for you to put together a powerful Internet resource, sharing your equipment and services with others.
