My neighbors and I made a home network between our PC's. The whole idea was to share one cable modem and broadband connection for using the Internet. Because of its speed, it can satisfy all our needs and we all would spend less money. However, that is not working. How to divide broadband connection among several programs and users?
It is not working because you did not share your internet connection on proper way. There are few ways to share internet connections. The thing you should do if you want to share cable internet connection is called port forwarding. You have to do that because all of you are sharing one static IP address. If you want to do that with software emulation, you must have some bigger experience. I must assume that you do not have that so let us get back to the hardware solution. To do port forwarding you will need a special device called network router. When you connect your network and cable modem to router, you will not have any further problems with accessing the Internet over DSL connection. The other thing you can do is to connect one computer to cable network and share its connection to everybody else. That way it will work as a gateway. The main disadvantage of that solution is that gateway machine should always be turned on.
