Port forwarding is a useful feature for gamers and those who run servers from their home networks. However, it can be tricky to set up, especially when using WiFi extenders. While port forwarding doesn't care if things are wired or wireless, the hosting box (destination) must be on the same subnet as the LAN port of the router. This can be an issue when using WiFi extenders, as they often create a new subnet, which can cause problems with port forwarding. In addition, some extenders may not support port forwarding at all, and users may need to check their device's specifications to determine if it is possible.

What You'll Learn
Port forwarding with wifi extenders
Port forwarding is possible with WiFi extenders, but there are a few things to keep in mind. Firstly, the extender itself should not impact port forwarding. However, it is important to ensure that your device has a public IP address, as port forwarding will not work without one.
To set up port forwarding with WiFi extenders, the hosting box or destination must be on the same subnet as the LAN port of the router. This means that if port forwarding occurs in Box1: (WAN)Box1(LAN) and the LAN is 192.168.1.x, then the final destination IP host must be within the same subnet. Having more than one subnet or router in your LAN can cause issues. In such cases, it is recommended to reduce to a single subnet, or alternatively, FP on each NAT box.
Additionally, when dealing with WiFi extenders, it is important to know the IP address assigned to the extender by the router. This can be found through the router's DHCP settings, associated with the extender's MAC ID or Address. The MAC ID can usually be found on a sticker under the extender unit.
In some cases, port forwarding issues may be related to the device itself. If other troubleshooting steps do not work, it may be necessary to check if the device is causing the problem. For example, data may be reaching the device, but the device is not responding. Ensure that there are programs running on the ports you are using.
Overall, while port forwarding with WiFi extenders is possible, it is important to consider the network configuration, IP addresses, and device settings to ensure a successful setup.

The impact of extenders on port forwarding
Firstly, it is important to ensure that the extender is set up correctly and is compatible with port forwarding. This involves verifying that the extender is connected to the router and that the IP addresses of the extender and router match. In some cases, issues with port forwarding may be due to incorrect IP configurations or problems with the extender's connection to the network.
Additionally, the number of subnets in the network can affect port forwarding. Having multiple subnets within the local area network (LAN) can cause issues with port forwarding. To resolve this, it is recommended to reduce the network to a single subnet. If this is not possible, port forwarding may need to be configured individually for each NAT box in the network.
Another consideration is the hosting box or destination device for port forwarding. The rule for port forwarding is that the hosting box or destination device must be on the same subnet as the LAN port of the router. If the destination device is connected through an extender, it is important to ensure that it is on the same subnet as specified in the port forwarding configuration.
Furthermore, the type of connection between the extender and the device can also impact port forwarding. It is generally recommended that the device connected to the extender via port forwarding uses a wired Ethernet connection rather than WiFi. This is because a wired connection can provide a more stable and lower-latency connection, which is important for certain applications such as gaming.
Lastly, the extender mode and network topology can introduce complexities. When using extender mode, it is important to understand the network topology and any potential double NAT (Network Address Translation) configurations. While it is possible to port forward with extenders in extender mode, it may require additional configuration, especially if there are multiple extenders or routers involved. In such cases, it is essential to ensure that the network is correctly configured to avoid issues with port forwarding.

Finding the IP address of the extender
Finding the IP address of a WiFi extender or repeater can be done in several ways. One method is to locate the "connected devices" window in your router settings while keeping the repeater turned on. Look for any strange devices with an address that doesn't match the default gateway IP address. In the browser, enter this IP address, which should open the repeater's page. Log in with the repeater's username and password to access its settings.
Another approach is to use network scanning tools like nmap, which can help identify the IP addresses of devices on your network. For example, running "nmap 192.168.0.0/20 -p 80" can scan for devices within a specified IP range.
Additionally, if you're using Windows, you can refer to the ipconfig report to find the default gateway IP address. This address typically leads to the main router's configuration page, but it may also provide clues about the extender's IP address.
In some cases, repeater manuals may suggest a specific IP address to connect to the device, such as 192.168.10.253. However, this may not always work, and you may need to explore other methods.
If the repeater's IP address cannot be found on the local network, it may be outside your local network. To access it, you can try disabling DHCP on your computer and setting your device's IP address within the range of your Access Point (AP) network.

Port forwarding for a Minecraft server
Port forwarding involves assigning a port on your router that is open to outside connections. This allows users with specific network information to connect to your Minecraft server.
Firstly, you must find your router's IP address to start the port forwarding process. To do this, open Run by pressing the Windows Key + R, then type CMD into the bar and press Enter. The next step is to set up a static IP address. This prevents your IP address from changing every time your device reconnects to your router. You can usually create a static IP address through your router settings.
Once you have done this, you can begin to port forward. While every router will have a different port forward setup process, they should all include sections for your IPv4 address and port settings. Before entering any information, make sure your service type includes TCP and UDP. Input your IP address, and put 25565 in for your port number. This is the default Minecraft port number. If you changed your server's port number during the Minecraft server setup process, you must go into your server properties and find it or switch it back to the default port number.
If your friends are still having trouble connecting to your Minecraft server, you may have to allow your Minecraft port through your system's firewall. Open the Control Panel and select Windows Defender Firewall, then click Advanced Settings in the following list. Select Inbound Rules on the left-hand sidebar, then select New Rule on the right-hand sidebar. Select Port from the list of rule settings, then click Next. Select either TCP or UDP, pick specific local ports, and enter 25565 into the text box. Select Allow the connection and click Next. Allow the default options for the Profile page and click Next. Name the rule Minecraft Server or whatever you prefer.
The extender should not have any impact on port forwarding. However, if you have >1 subnet or >1 routers in your LAN, this may cause issues with port forwarding.

Troubleshooting port forwarding issues
Port forwarding is a process in which data traffic is intercepted from a computer network and redirected to an IP or port. It is a powerful tool for accessing devices and services on your network from outside your home or business. However, it can be frustrating when things don't work as expected.
Firstly, check your router settings. Make sure that the port you are trying to forward is not already in use by another device or service. Verify the internal IP address of the device you are connecting to, as incorrect mapping is a common issue. If you are using port forwarding to access a device on your network remotely, you will need to include the port number at the end of your hostname to connect to the correct device. For example, if your hostname is "http://yourname.ddns.net" and you are trying to access a web server running on port 80, you would need to use the hostname "http://yourname.ddns.net:81".
If you are still having issues, the problem may be caused by your PC. The data may be getting to the PC, but the PC is not responding. There must be programs actually running on the ports you are using. Also, check that the correct protocol (TCP or UDP) is being used and that the forwarding rule is correctly configured.
If you can't access the port on the local network, it's likely that the device is not accepting connections, so it may be a firewall issue. It is worth noting that antivirus software can sometimes block pop-ups and interrupt the connection.
If you are still having issues, you may need to contact your ISP to request that they forward a port for you. You can also try online forums and communities for insights and solutions from people who have faced similar challenges.

Frequently asked questions
Port forwarding doesn't care whether things are wired or wireless. The only rule is that the hosting box (destination) must be on the same subnet as the LAN port of the router. The extender should not have any impact on port forwarding.
First, be sure the external IP that shows on your router matches the IP on WhatsMyIP or on tools that scan for open ports. If you do not have a public IP, you cannot make port forwarding work. You may need to know the IP address assigned to the network extender by your router in order to forward ports.
People get into trouble by having more than one subnet and more than one router in their LAN. In this case, you should reduce to one simple subnet. If you can't, then you must FP on each NAT box.
