Opening port 8444 on Xiaomi router: the full guide

Port 8444 is critical to decentralized networks like Chia Network and game servers. If you own a Xiaomi router, you’ll need to set up port-over-port rules known as Port Forwarding to work properly, without which your device will be behind the NAT, limiting incoming connections and reducing application efficiency.

Xiaomi router setup process has its own features related to the MIWiFi shell, which may differ from standard interfaces of other manufacturers. In this article, we will discuss in detail each step: from fixing to fixing the device. IP-You'll learn how to configure the virtual server correctly and check the results of your work.

Before you start making changes to the web interface, you need to prepare the computer or server on which the target application is running. Make sure you have access to the router administrator panel and understand the basic principles of how the local network works.

Why do you need port transfer and how does NAT work?

Technology NAT (Network Address Translation allows multiple devices on your home network to use a single public network. IP-The router acts as an intermediary, redirecting requests from the outside world to specific devices within the local network. By default, however, the router blocks all incoming connections that were not initiated from the inside, creating a barrier for server applications.

When you open port 8444, you're actually creating a permanent rule in the routing table, and that rule says, "All traffic coming to port 8444 from the Internet must be transmitted immediately to a particular location." IP-For Chia miners, this means being able to accept blocks and interact with other nodes on the network without delay.

⚠️ Warning: By opening ports, you make your device visible to the outside world. Make sure that the software that uses the port is updated to the latest version and does not contain security vulnerabilities.

It is important to understand the difference between static and dynamic. IP-If your computer's address changes after each router reboot, the rollover rule will stop working because it's tied to a specific numerical value, which is why the first step is always to fix the address.

Preparation: static consolidation IP-address

The first and most important step in setting up is to assign your computer or server a permanent local address. On Xiaomi networks, this can be done through the anchoring function. MAC-address IP, This ensures that the settings remain unchanged even after the equipment is restarted.

First you need to know. MAC-the address of the network interface of the device that will use the port 8444. On Windows, this is done via the command line by the ipconfig command. /all, a on Linux or macOS via ifconfig or ip addr. Write down this address, it will be needed to configure the router.

Then log in to your Xiaomi router's web interface. Usually the access address is 192.168.31.1 or miwifi.com. After authorization, go to the LAN or DHCP Server settings section, where you need to find a list of connected customers and select your device.

• 📱 Find your computer by name or in the list of devices. MAC-address.
• 🔒 Click on the edit or customization button for the selected client.
• 📌 Select the option “Secure” IP» (Set Static IP) or manually enter the desired address, for example, 192.168.31.100.
• 💾 Save the changes and make sure the device gets a new address.

Once the address is fixed, it is recommended to restart the computer and check that it does receive the reserved IP. This is the foundation for further work, since without a permanent address, the NAT rule will drive traffic to nowhere.

Entrance to the Administrator Panel of Xiaomi router

MIWiFi may look different depending on the firmware version, but the logic remains the same. Accessing advanced settings often requires switching to Advanced mode, which is usually in the upper right corner of the screen.

In standard mode, many important functions, including manual port configuration, can be hidden, so immediately after logging in, look for the Common Settings and Advanced Settings tabs, and we'll need the second option for deep network configuration.

If you use the Mi WiFi mobile application, the functionality may be limited. To fully configure port port port port port transfer, it is highly recommended to use the browser on your computer, since the mobile version of the interface is often stripped down and does not contain all the necessary fields.

Make sure you are connected to the router via cable or a stable Wi-Fi connection. A communication breakdown when you make changes to your network settings can result in loss of access to the control panel, which will require the device to be reset before factory settings.

Port Forwarding (Port Transfer)

The main section we are interested in is usually called “Port Forwarding”, “Virtual Servers” or “NAT” in the Xiaomi interface. In the Russian version, look for “Ports Overshoot” or “Virtual Servers” in the Advanced Settings menu.

You'll need to create a new rule here, press Add or plus, and you'll open a form where you want to type in the settings. The name of the rule can be anything, like, for example, «Chia_Node» or «Game_Server», So you can easily identify them on the list.

In the Protocol field, select TCP, as port 8444 for Chia Network and most server applications uses this protocol. Some routers allow you to choose TCP/UDP or All, which is also acceptable, but may be less secure.

Parameters of the rule:


Name: Chia_8444




Internal IP: 192.168.31.100 (Your static IP)




Internal Port: 8444




External Port: 8444




Protocol: TCP

The "Internal Port" and "External Port" fields must match and equal 8444. In the "Internal IP" field, type in the address you assigned to your computer in the first step. After filling in all the fields, click "Save" or "OK" to apply the settings.

💡

If there is already a record with port 8444 on the rule list, delete it or change it to avoid a rule conflict.

Firewall setting and traffic filtering

Xiaomi routers often have a basic firewall built in, which can block incoming connections even if there is a pass rule. Check the "Security" or "Firewall" section in the settings. Make sure the protection level is not set to "High" if this blocks legitimate traffic.

Sometimes you need to add an Allow Rule separately from port rollover, depending on the firmware version. If you have Port Forwarding setup, look for the Filter or Access Control tab.

Also worth paying attention to is UPnP (Universal Plug and Play) feature, which allows apps to automatically open ports for server tasks like mining, manual setup is always more reliable and safer. UPnP can become a security hole if malware gets to your network.

• 🛡️ Check if the Anti-Attack function is activated, which can block frequent connections.
• 🔓 Make sure that in the settings WAN There is no ban on incoming connections (WAN Access Control).
• 📡 If used IPv6, Configure the firewall rules for the sixth version of the protocol, as IPv4 and IPv6 work independently.

⚠️ Note: In some regions, providers use CGNAT, giving you a gray» IP-In this case, port port port port port port porting on the router will not help until you switch to the tariff with white» IP.

Open port inspection and diagnostics

After saving all the settings, it may take a few seconds for the router to apply the rules. To check if port 8444 is open, use online port checking services, such as PortCheckTool or 2ip.ru.

Important: When checking, an application using a port (such as a Chia wallet) should be launched and actively try to establish a connection. If the program is closed, the port will appear closed, even if the router settings are correct.

Enter port number 8444 in the site check box and click Check. If the result is "Open" or "Open", then the setup was successful. If the status is "Closed" or "Filtered", check the Windows firewall or antivirus on your computer, as they can block the connection locally.

For a deeper diagnosis, you can use the command line. The command netstat -an | find "8444" will show whether your application listens to this port locally. If the lines with LISTENING are not, the problem is on the program side, not the router.

Possible problems and solutions

One of the common problems is dual NAT. This is a situation where your Xiaomi router is facing another router from the provider, in which case you need to either configure the airbrush on the first router or switch the ISP router to Bridge Mode.

You can also get lost when you update your router firmware. If you upgrade MIWiFi OS, check the Port Forwarding section again. Sometimes it makes sense to take a screenshot of the settings or write them down manually before upgrading.

If nothing works, try temporarily disabling your computer firewall for verification. If the port opens, you should create an exception in the antivirus or Windows firewall for a particular application, rather than open the port globally.

💡

The main reason for the failure is not the settings of the router, but the “gray” IP from the provider or blocking the antivirus on the computer itself.
