Chapter 10  

Network Security  

10. 1. Firewall & DoS Protection  

The SPI (Stateful Packet Inspection) Firewall and DoS (Denial of Service) Protection  

protect the router from cyber attacks.  

The SPI Firewall can prevent cyber attacks and validate the traffic that is passing  

through the router based on the protocol. This function is enabled by default, and it’s  

recommended to keep the default settings.  

DoS Protection can protect your home network against DoS attacks from flooding your  

network with server requests. Follow the steps below to configure DoS Protection.  

1. Visit http://tplinkmodem.net, and log in with your TP-Link ID or the password you  

set for the router.  

2. Go to Advanced > Security > Firewall & DoS Protection.  

3. Enable DoS Protection.  

4. Set the level (Low, Middle or High) of protection for ICMP-Flood Attack Filtering,  

UDP-Flood Attack Filtering and TCP-Flood Attack Filtering.  

•

•

•

ICMP-Flood Attack Filtering - Enable to prevent the ICMP (Internet Control  

Message Protocol) flood attack.  

UDP-Flood Attack Filtering - Enable to prevent the UDP (User Datagram  

Protocol) flood attack.  

TCP-Flood Attack Filtering - Enable to prevent the TCP (Transmission Control  

Protocol) flood attack.  

5. Click Save.  

Tips:  

1. The level of protection is based on the number of traffic packets. Specify the level at DoS Protection Level  

Settings.
