QUESTION POSED ON: 12 December 2008
I have a Pentium 4 desktop PC on which an email server program is running. We are connected to the Internet via a router. We have a Class C network.
Many times we have found users who are not authorized for Internet, use the router IP address as a gateway and access to the Internet. Normally, our practice is to change the node address of the router (for example, if originally it was 192.168.1.1, we change it to 192.168.1.200).
Now I want to change the IP addressing of the router and make it 192.168.10.1. However, when I do this, none of the authorized users can access the Internet since the class of the network of the router changes. How do I implement this change and have the authorized users access the internet?
