How to Change NETGEAR Firewall Settings
You do not have to use your computer's operating system to set up a NETGEAR firewall. If you use a wireless network with a NETGEAR router, you can utilize the router's configuration page to change the firewall settings. Using this will allow you to block and allow incoming and outgoing wireless traffic and data. This will protect your computer from potential viruses and other malware.
