To protect the home network from malicious attacks and harmful information, the firewall function of the router is particularly important. This article will introduce the firewall function of the router in detail to help you better protect the home network security. Firstly, the basic protection function of the router's firewall can monitor network traffic in real time, intercept suspicious and malicious network access, and effectively prevent network threats such as hacker attacks and virus propagation. Secondly, the access control function can restrict the access permissions of the internal network to the outside world by setting access control rules, preventing unauthorized devices or users from accessing the home network. Thirdly, some advanced routers have parent control functions that can limit children's online time and access to specific websites to protect children from the influence of bad information. Fourthly, the router firewall adopts advanced intrusion detection and defense technology to discover and stop network attacks in a timely manner to protect the security of the home network.

To set up the router firewall, you should:

Set a complex password for the router to prevent others from maliciously accessing the home network. Regularly update the firmware of the router to obtain the latest security patches and function updates. Regularly check access records to understand the access situation of the home network and discover and handle suspicious access in time. If necessary, activate the parent control function and set appropriate online strategies to protect children from bad information. In conclusion, the firewall function of the router is an important means to protect the home network security. By understanding and properly setting up the router firewall, we can effectively prevent network threats and protect the family from harm.
