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.

A login window opens.
