Wireless routers are quickly becoming an important device. Wireless routers help you connect several computers simultaneously to the internet in one go and that too, wirelessly. A common setting for a network router is firewall configurations. A firewall blocks unauthorized access from the internet to the internal network. The Netgear firewall also allows access to the internal network using port forwarding. This blog states on how to configure a Netgear firewall
