Configuring firewall settings
The gateway’s default firewall settings block unwanted access from the Internet. Most

If necessary, you can modify the firewall settings to allow certain Internet traffic or
users through the firewall to devices on your home network.
Hosting an application
To allow access from the Internet to applications running on computers inside your
home network, you need to open firewall pinholes and associate the intended
application with a computer connected with your gateway. If you cannot find a listing
