development historyIn 2001, Huawei released its first firewall card, and since then, with the development of networks and changes in technological requirements, it has continuously launched generation after generation of firewall and security products.

Working modeRouting mode: The interface of the firewall connecting to the network is configured with an IP address. When it is located between the internal network and the external network, the interfaces connected to the internal network, external network, and DMZ areas need to be configured with IP addresses for different network segments. At this time, the firewall is first a router and then provides other firewall functions.Transparent mode: The firewall is connected to the outside world through the second layer, and the interface has no IP address. It only needs to be connected to the Huawei firewall in the network like a switch. The internal and external networks must be in the same subnet, and messages are not only exchanged at the second layer in the firewall, but also subjected to high-level analysis and processing.Mixed mode: Firewalls have interfaces that work in both routing mode and transparent mode, and are currently mainly used in special applications that provide dual machine hot standby in transparent mode.

Huawei router products are diverse, covering multiple series such as home and enterprise use, with features such as high-speed internet access, wide signal coverage, and strong security protection. The following is a detailed introduction:Home router:Huawei Router WS6502: it adopts a gigabit network port design and gigabit Wi Fi to meet the high-speed fiber broadband access needs. Supports dual band integration, automatically selects 2.4GHz or 5GHz frequency bands. Four external high gain omnidirectional antennas with strong signal penetration capability through walls. It can also intelligently recognize mainstream mobile games, establish a dedicated channel when opening the game, significantly reduce latency by 20%, and support children's internet protection and HUAWEI HomeSec security protection functions.

A firewall is a network security system designed to monitor and control network traffic, determining whether to allow packet transmission based on predefined security rules. Its main function is to protect the internal network from external threats, prevent unauthorized access, and establish a security barrier between the enterprise network and the Internet. By filtering traffic, preventing malicious attacks, and recording network activity, firewalls effectively enhance the security and stability of the network. As the first line of defense for network security, firewalls play a crucial role in the network environments of enterprises, institutions, and individual users.

Huawei Firewall is a network security product series launched by Huawei, aimed at providing comprehensive network threat protection, access control, and traffic management functions for enterprises, operators, and data centers. Its products cover various forms such as hardware firewalls, virtualization firewalls, and cloud firewalls, adapting to the needs of multiple scenarios

Eudemon series: Early high-end firewalls mainly used for operators and large-scale network boundaries.

Virtualization firewall: such as vFW, suitable for cloud environments (such as Huawei Cloud, private cloud).

Cloud firewall: such as Huawei Cloud Anti DDoS, Web Application Firewall (WAF), etc.

Huawei Firewall is the core product of Huawei's network security solution, covering functions such as boundary protection, intrusion prevention, data leakage prevention, advanced threat detection, etc. It is widely used in government, finance, operators, enterprises and other fields. Huawei Firewall is known for its self-developed chips, AI intelligent engine, and high reliability, and has a stable market share in the global firewall market (according to Gartner data)
