Chapter 5. Network Security
5. 1. Protect the Network 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.
Follow the steps below to configure Firewall.
1. Visit http://mwlogin.net, and log in with the password you set for the router.
2. Go to Advanced > Security > Firewall and DoS Protection.
3. Enable IPv4 SPI Firewall.
4. Enable DoS Protection.
Note:
DoS protection and Traffic Statistics must be enabled at the same time. To enable Traffic Statistics, go to System >
Traffic Monitor and toggle on Traffic Monitor.
5. 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-SYN (Transmission
Control Protocol-Synchronize) flood attack.
Tips:
The level of protection is based on the number of traffic packets. The protection will be triggered immediately when the
number of packets exceeds the preset threshold value (the value can be set on Dos Protection Level Settings section
of the same page), and the vicious host will be displayed in the Blocked DoS Host List.
6. Click Save.
5. 2. Service Filtering
With Service Filtering, you can prevent certain users from accessing the specified
service, even block internet access completely.
