I on the network router port 8080, 8080 port forwarding to the server that can access the server IP: 8080 is able to directly access to my network routers exchange

CodePudding user response:

No problem if it is a device should be no problem, direct socketsend, source address, destination address is received if back to the message to other equipment of the network, need the second device prior to the server send a message, because involves the NAT, or NAT devices don't know which is forwarded to a network device
