To map the internal IP of an H3C router to the external network, it is usually necessary to use Port Forwarding or Virtual Server functionality. The following are general steps and precautions: 1. Log in to the router management interface
Log in to the H3C router's management interface using default or custom login credentials. 2. Configure port forwarding or virtual server
#Port Forwarding
Go to the "Firewall" or "Security Settings" section.
Select 'Port Forwarding' or similar options.
Add a new forwarding rule that specifies the IP address, port number, and protocol type (such as TCP/UDP) of the internal server.
Set the external port, which is the port number of the public IP, to ensure that it matches the port that the internal server is listening on (if you need to forward traffic outside of a specific port, you can set a different external port number).
#Virtual Server
If the router supports more advanced virtual server configurations, you can enter the corresponding settings interface.
Configure rules similar to port forwarding, but may also include more advanced options such as domain based virtual hosting. 3. Save and apply settings
After completing the rule configuration, be sure to save and apply the settings to ensure that the configuration takes effect. matters needing attention
Make sure your H3C router has obtained the public IP address, because the intranet IP (such as 192, 168, x.x) cannot directly access the Internet.
Port forwarding may increase security risks as it exposes certain ports of the router to external networks. Ensure that your router and password are sufficiently secure, and regularly update firmware to obtain the latest security protection.
If the router is connected to multiple LAN devices, please ensure that the DHCP service is configured correctly so that clients can obtain the correct gateway and DNS information.
If you are not familiar with the specific configuration, it is recommended to refer to the official documentation of H3C router or contact technical support for more detailed guidance.
