Issue Description

What Is the Principle of IP-MAC Address Binding?

Solution

After the firewall receives packets, it searches for corresponding entries based on the source IP addresses of packets. If such entries are found, the firewall compares the MAC addresses of entries with the source MAC addresses of the packets. If their MAC addresses are different, the firewall discards the packets. If their MAC addresses are the same, the firewall forwards them.
