Why Use a NAT Router?
Every computer connected to the Internet is exposed to dangers. For myself and many others the benefits of using the Internet far exceed the possible dangers. We can minimize the dangers if we follow some basic security principles both for our home and office computers. Let’s start with how we connect to the Internet using a wired connection. Many home users and small businesses connect to the Internet through a Cable/DSL modem. This type of connection is an always on connection. As long as our computers are powered on we are connected to the Internet and exposed to dangers. We increase the danger if we connect our PC directly to the Cable/DSL modem. Computers connected in this way will receive a DHCP public IP address from their Internet Service Provider. What this means is that our PC is both visible and accessible directly from the Internet. This exposes us to Internet scanning, worms, and hackers. If we don’t have a software firewall installed then our PC can be easily compromised
