Manage NAT Filtering

Network Address Translation (NAT) determines how the modem router processes inbound traffic. Secured NAT protects computers on the LAN from attacks from the Internet but might prevent some Internet games, point-to-point applications, or multimedia applications from working. Open NAT provides a much less secured firewall but allows almost all Internet applications to work. Secured NAT is the default setting.

To change the default NAT filtering settings:

1.Launch an Internet browser from a computer or WiFi device that is connected to the network.

2.Type http://www.routerlogin.net or http://www.routerlogin.com.
