(I recommend you a free ARP firewall software that is stable and reliable, easy to use and has good protection ability - Ice Shield ARP Firewall, ARP spoofing attacks are rampant, many personal and unit computers and website servers are spoofed by ARP, either the Internet is disconnected or the Internet is disconnected. The account and password are stolen, and the damage is very large. Although there are many ARP firewall software on the Internet, the test found that most of them have disadvantages such as complicated installation and settings, unstable operation, poor compatibility and occupying a lot of system resources. The Shield Technology team specially designed and developed a stable and reliable ARP firewall software for everyone to use. I wish everyone to be free from ARP spoofing attacks in advance.)
