Remote monitoring of router settings also promotes the updating and upgrading of routing technologies. Here we have explained how to set up a TP-LINK router. Remote monitoring system clients access via public network (WAN) WEB. Monitoring host, how to operate? If the monitoring host is connected to the Internet through dial-up Internet access and private line, not through the router. Then the operation steps are the same as in the local area.
If the monitoring host end accesses the Internet through the router, then all ports used by the software must be opened for port mapping and other operations. Then how to open the port. Here we take the TP-LINK router as an example to introduce . Query the IP information of the local machine and the router through the start menu ————enter“CMD” and enter the DOS operating state—— input“IPCONFIG” query the IP information, where IP Address represents the Machine IP address, Default Gateway represents the gateway (or router) IP address. Specific steps (recommended to use method 2):
1. Enable DMZ virtual host: This operation is the easiest way to map the external IP address of the TP-LINK router directly to the DVR host on the internal network; The disadvantage is that the DVR host is directly mapped to the external network, which exposes the DVR directly to the public network and is particularly vulnerable to attacks and viruses.
2. Port Mapping: This method is a relatively safe operation method. It only opens useful ports, effectively shields attacks from external networks, and remotely monitors port 80 through client software. 81 port or other. Each port involved in the software has different functions and must be fully open. For ease of management, set the internal IP of the monitoring host to fixed, and try to avoid the IP address conflict with other computers. Enable router port mapping operation step-by-step (TP-LINK router as an example):
1. Enter the router IP in the IE address bar;
2. Enter the username and password (default user name) Admin, password admin);
3, click on the web page from the top left to the bottom of the fifth item & ldquo; forwarding rules ”;
4, click “ virtual server”< /p>
5, the server port in the right window of the device (in each entry: 80 or 81, 5050, 5051, 5052, 6789, 5040, 7050), IP address (that is, monitor the host network IP address) , protocol (select ALL), enable (check all), save it after input correct. Note: Since the software involves many ports, some routers only support several ports. For example, the TP-LINK router we introduced can only open 8 ports. If you need to open multiple ports, you can replace the router that supports multiple ports.
