Looking back, a little effort goes a long way, andyears of hard makes the book.
Movingforward, difficult technologies scare no one, and we gear up for the newjourney.
Monthafter month and quarter after quarter, season 2 of Learn Firewalls with Dr.WoW has finally been unveiled. While racing with time, Dr. WoW hasaccomplished a lot. Dr. WoW has sorted out the posts of season 1, made somecorrections and improvements, and worked with the publishing house to proofreadand finalize the book. Dr. WoW's team has also made a side-by-side comparisonbetween products and recorded video tutorials. Through the experience of thelast half year, Dr. WoW deeply feels that there is always something to learnabout firewalls, and that the hardship in studying firewall technologies isbeyond words. Fortunately, Huawei Firewall Technologies has beensuccessfully published, and Dr. WoW is full of joy and energy again.
Inthe second season, Dr. WoW will introduce content security features, such asantivirus, intrusion prevention, URL filtering, and mail filtering, and otherfunctions, such as user management, virtual systems, and bandwidth management.Dr. WoW will describe these features and functions of Huawei next-generationfirewall (NGFW) and the configuration procedures. Dr. WoW hopes that the postscan help readers understand the technical mechanisms and configuration methodsof NGFW. Dr. WoW encourages readers to interact and discuss questions online tomake progress together.
Thebest reward of learning is the thrill of discovery. It has nothing to do withfame. For a network engineer, no money, no fame, and no material object cancompare to the joy and satisfaction from getting a network up and running orlocating a fault. We never forget why we started to accomplish what we want.Digging into technologies is no easy job. However, we embrace the challengesand will continue this road.

Networks are changing fast, and networking devices have taken the spotlight one after another. You may be quite familiar with routers and switches, but with firewalls, probably not so much. As loyal safeguards for network security, firewalls keep a weather eye on threats, and no packet can get through without the permission of firewalls. Now, it's time to get familiar with these heroes. Welcome to the Dr. WoW series technical posts. Dr. WoW will take you on an adventurous journey to the world of firewalls.
For readers to conveniently read the technical posts in the forum, Dr. WoW sorted out all technical posts, added another four configurations examples for deploying firewalls in typical scenarios, and converted them to PDF files for readers to download. All readers are welcome to download the PDF file collection in the attachments to learn knowledge, master configuration methods, and become firewall technical experts.
