Go for a router with advanced features

One of the basic network connectivity devices is a router. A router transfers network packets between two different networks. In order for network traffic to get from one computer to another on the Internet, this traffic normally has to traverse a number of routers. Some router manufacturers have enhanced the functions of their products by including firewall features.

If you already have a router that connects your network to the Internet, you should explore whether it can perform packet filtering or other firewall functions. Most likely, you will find that your router provides some rudimentary firewall capabilities but that it doesn’t give you any advanced features.
