the remote WAN. Generally, the ISP line and the peer router of WAN
or other network devices are interconnected to realize long-haul data
transmission. During data transmission, the path to the destination
is selected according to the address information in the packet, and
this process is called “routing”.

the packet content. It can specify the packet source and destination
address and other more information. In addition, the state
inspection firewall also closes the port, till the specific port request
