Foreword: Recently, the company has a project, and the medical insurance needs to set up router port mapping; I will first use the company's monitoring to do debugging; access the internal Hikvision video recorder through the company's external network ip+port number; (the video recorder ip has been mapped and jumped on the router , I won’t go into details here.) The steps are as follows
login device
Log in to the WEB interface (by default, the login address is 192.168.1.1, the login account is admin, and the password is admin), select "NAT Configuration > NAT Configuration" in the navigation bar, and click the "Internal Server" tab to enter the internal Server configuration page
Configure port mapping
#Select the interface as the external network port of the device, select TCP for the protocol type, and generally select the current interface IP address for the external IP address. If the operator has allocated multiple public network addresses, you can also choose to use other addresses. The external port can be filled in freely. In this example, select 8080. For the internal IP address, fill in the intranet WEB server address 192.168.1.100. For the internal port, select the port number provided by the internal server. In this example, it is http service, that is, port 80. After the configuration is complete, click "OK".
save configuration
# After completing the above settings, first click OK, then click "Save" in the upper right corner of the device web page to save the configuration
Look at the effect; the external network ip+port directly accesses the monitoring of the internal network 192.168.1.248:81
