Philips SNB5600 manual MAC Filter, URL blocking, Schedule rule, Intrusion detection

Network attacks that deny access to a network device are called Denial-of-Service (DoS) attacks. DoS attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resources.

The Wireless Router firewall function protects against the following DoS attacks : IP Spoofing, Land Attack, Ping of Death, IP with zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.

The firewall does not significantly affect system performance, so we advise leaving it enabled to protect your network. Select "Enable" and click the "SAVE SETTINGS" button to open the Firewall submenus.

Intrusion Detection Feature

Stateful Packet Inspection (SPI) and Anti-DoS firewall protection (Default : Enabled) - The Intrusion Detection Feature of the Wireless Router limits access for incoming traffic at the WAN port.
