Protocol TCP+UDP: the specified source IP can ping the destination IP address, but cannot establish
TCP/UDP connection.
Protocol ICMP: the specified source IP cannot ping the destination IP address, but can establish
TCP/UDP connection.
Here we test with TCP protocol to disable a port of the LAN device from accessing a specified port of the
destination IP.
Leave the source zone as default, fill in the source IP address or MAC address.
Here we disable a device with the MAC 4C:ED:FB:6A:F4:60 and port 8800 from establishing TCP connection
with the destination IP 192.168.21.200 and port 8899.
Leave the source port and destination port to null means disable the TCP connection between the source
device(4C:ED:FB:6A:F4:60) and the destination address 192.168.21.200.
