Realization method of port forwarding based on client host name in router

Abstract

The invention discloses a realization method of port forwarding based on a client host name in a router. The realization method comprises the following steps: S1, a router establishes a background server to monitor the change of client equipment list information; S2, the router lists client equipment names according to the client equipment list information for user selection, and sets forwarding port information, and sends MAC addresses corresponding to the client equipment names and the forwarding port information to the background server; S3, the background server queries the IP address of client equipment according to the received MAC address of the client equipment, establishes a port forwarding list and saves the MAC address and the IP address of the client equipment and the forwarding port information; and S4, a port forwarding rule is established according to the IP address and the forwarding port information in the port forwarding list, thereby realizing the port forwarding of the data information. By using the method disclosed by the invention, an administrator does not pay attention to the change of the client equipment IP address and the modification of the equipment name in real time, thereby effectively relieving the workload of the network administrator.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an implementation method of port forwarding based on client host names in routers. Background technique [0002] At present, the Internet of Things is developing vigorously, but IPV6 has not yet been widely used. In our country, IPV4 is still the mainstay, and the IP public network address in the IPV4 protocol cannot meet the needs of devices in the Internet of Things. In order to solve this problem, a router is used, which can basically meet the needs of the device to access the Internet. However, if you want to set up a server in a LAN device, you cannot directly access it in the WAN and other LANs. You must use the port forwarding of the router. to realise. As we all know, the port forwarding rules of routers are based on the IP address of the client host for port forwarding. Therefore, it is necessary to obtain the IP address of the client host. There are two met...

Problems solved by technology

However, if the network segment of the router changes, the IP address of the device must also be reset

If you forget to reset, the IP address of the device may not belong to the same network segment as the router, and it will not be able to forward

If there are many devices in the local area network, and each device needs port forwarding, then each device needs to reset the IP address one by one, and it is not possible to miss any one. This kind of setting is very cumbersome, heavy workload, time-consuming and labor-intensive.
