If you're having trouble opening ports on your Airport Time Capsule, you're not alone. This is a common issue with Apple's Airport Time Capsule router, and there are several reasons why port forwarding may not be working. One reason could be a Double NAT error, which makes port forwarding difficult or impossible to configure correctly. To resolve this, ensure your Airport Time Capsule is the only router on the network and that you have a public IP on the WAN interface. Additionally, you'll need to download the AirPort Utility app to access the router's settings and configure port forwarding. If you're still having trouble, consider using a port forwarding add-on like PureVPN, which simplifies the process and ensures your network's security.

Port forwarding with Airport Time Capsule
Port forwarding on an Airport Time Capsule router can be a complicated task. There are several reasons why port forwarding may not work on your Apple Time Capsule router.
To port forward your Airport Time Capsule, you need to open the "AirPort Utility" app on your device and navigate to Summary -> Advanced -> Port Mapping -> "+" or "Add." Enter the IP address of your device and the port numbers to create the new port forwarding rules, then hit "Save."
The process is similar to other routers, but you will need to download the "AirPort Utility" app to access the router's settings for configuring port forwarding. Before you begin, ensure that your device is connected to your Airport Time Capsule router.
In the Network section, "Router Mode" must be set to "DHCP and NAT." This will enable the "Port Settings" section. To forward ports, click the "+" to add an entry to the "Port Settings." Give it a description, fill in the public and private ports, and the IP you want to forward traffic to.
If you are still facing issues, you may want to consider a port forwarding add-on like PureVPN, which simplifies the process and ensures your network's security. This can be especially useful if you are facing issues such as CGNAT or struggling to navigate the settings on your operating system.

Double NAT error
A Double NAT error occurs when you have two routers connected to each other in the local network, and each one of them is performing NAT on their upstream ports. One router is connected directly to your ISP (The Edge Router), and the other router is daisy-chained to it (The Daisy Chained Router). It is called Double NAT because there are two instances of NAT in the local network, but the Edge Router should be the only one performing NAT.
The issue with Double NAT is that hosts connected to the Daisy Chained Router could forward packets to the Internet, but it can be difficult for them to send packets to hosts connected to the Edge Router. As your packet has to go through NAT multiple times, this affects network performance both locally and when surfing the Internet. This can be a problem for online gamers or those using port forwarding rules and Universal Plug and Play (UPnP).
To fix a Double NAT error, you can remove the ISP-provided router from your network. If you have two separate ISP devices, a modem and a router, turn off and unplug the ISP-provided router, then connect your modem directly to your Wi-Fi device. If your ISP-provided router is combined with the ISP's modem in a single device, enable bridge mode on your modem/router combo to fix the Double NAT issue. When you enable bridge mode on your ISP router, it will turn off its NAT and allow your Wi-Fi device to be the sole device that performs NAT.
Another solution is to disable NAT on the internal router and add a static route in the edge router. You can also use a VPN such as PureVPN's port forwarding add-on, which is designed to bypass CGNAT and enables you to forward ports on your AirPort Time Capsule router easily.

PureVPN's port forwarding add-on
Port forwarding is a technique used to open routes directly for others to your device. Routers and home/work/school networks may have them completely blocked. This is where PureVPN's port forwarding add-on comes in.
The port forwarding add-on allows you to specify which ports to open or close. Once you enter the desired ports, you connect to a port forwarding-supported server in the PureVPN app. After connecting, the specified ports are redirected to your device, allowing external traffic to reach it directly, all while maintaining the privacy and security of a VPN.
To port forward your AirPort Time Capsule, you need to open the “AirPort Utility” app on your device and navigate to Summary -> Advanced -> Port Mapping -> “+” or “Add.” Then, enter the IP address of your device and port numbers to create the new port forwarding rules and hit the “Save” button.
With PureVPN's port forwarding add-on, you can open or forward ports in a hassle-free manner. You can enable or disable ports on your preferred device without having to delve into your router's settings. You can open up to 15 ports at the same time, perfect for hosting personal servers or managing multiple devices.

Router mode
If you're having trouble opening ports on your Airport Time Capsule, there are several things you can try. Firstly, make sure you have the AirPort Utility application installed on your computer or mobile device. This application can be downloaded from Apple's website. Once you have the application, follow these steps:
- Connect your computer or mobile device to your Airport Time Capsule.
- Launch the AirPort Utility application.
- Navigate to the "Summary" section and then click on "Advanced".
- Click on "Port Mapping" and then on the "+" or "Add" button.
- Enter the IP address of your device and the port numbers you want to forward.
- Click on "Save" to create the new port forwarding rules.
Additionally, you can try turning off routing and/or NAT on the Time Capsule by going to "Network" and selecting "Router Mode: Off (Bridge Mode)". This will disable any wireless networks created by your Time Capsule and pass the IP address assignment to your primary router.
If you're using a VPN, you may need to try a different router as Apple products can be difficult to work with when it comes to networking features.
Another option is to use a service like PureVPN, which offers a port forwarding add-on that allows you to bypass CGNAT and forward ports on your Airport Time Capsule easily without technical expertise. Simply subscribe to PureVPN, download the app, log in, and customize your port settings.
Finally, make sure that your Ethernet cable is connected correctly. If you're using a Netgear router, connect the cable from a LAN port on the router to the WAN "O" port on the Time Capsule. Reset the Time Capsule to its default settings and set it up again, making sure to turn off WiFi if you don't want it to provide a wireless signal.

Port settings
To enable port settings, the "Router Mode" in the Network section must be set to "DHCP and NAT". This will allow you to forward ports by clicking the "+" button to add a new entry. You will need to provide a description and fill in the public and private ports, as well as the IP address you want to forward traffic to.
It is important to note that a Double NAT error may occur, which can make port forwarding difficult or impossible. In this case, you may need to keep your device in bridge mode or explore alternatives such as PureVPN's port forwarding add-on, which is designed to bypass CGNAT and simplify the port forwarding process.
Additionally, the specific ports you need to open will depend on the application or device that requires port forwarding. For example, Xbox Live and remote access to a home media server will require different ports to be opened. Therefore, it is recommended to check the documentation of the relevant application or device for specific port requirements.
