Jazztel, a Spanish telecommunications company, offers telephone, television, and internet service. But to get the best of Jazztel, you may have to forward a few ports.
Port Forwarding helps users communicate with external servers more efficiently to attain much more stable connections and an improved internet experience.
Got no idea how to forward ports? Here is a complete guide to successfully managing Jazztel router port forwarding.
Why is Port Forwarding a Problem on Jazztel?
One of the main reasons Port Forwarding on Jazztel can be problematic is that many ISPs use Carrier-Grade NAT (CGNAT) to conserve IP addresses. Your ISP assigns a single IP address to several users, and all rely on that IP address.
What is CGNAT?
CGNAT stands for Carrier Grade Network Address Translation. Most ISPs, including Jazztel, use CGNAT to conserve their IPv4 pool. The IPv4 protocol only supports 4 billion IP addresses. ISPs perform CGNAT to assign a single IP address to multiple users, saving their depleted IP pool.

- Apply your desired port settings (scroll below).
- Click Apply settings.
How to Port Forward Jazztel – Step-By-Step Guide
Before forward ports for the Jazztel router, assign a static IP to your device. Here are the detailed instruction for the port forwarding procedure:
- Open a web browser.
- Access the SmartAX Jazztel settings by entering your router’s IP in the address bar.
- Enter the login credentials (type admin as both the password and the username).
- Even if the credentials do not work, you can always reset them.
- Once you have access to the Jazztel dashboard, navigate to the Port forwarding section.
- Now add a new port forwarding rule by selecting Add New / Create.
- Specify a name for the rule (any name will do).
- Now enter the static IP address for your device.
- Type in the port range you want to forward.
- You can add the same port in both fields if you do not have a range.
- Set a protocol for the Jazztel router as TCP, UDP, or both.
- In the External IP addresses field, type 0.0.0.0.
- Select the Enable checkbox.
- Make sure to save these configurations.
Fix Double NAT with Jazztel in Spain
You can’t use a public IP address that can easily port forward on Starlink. However, you can resolve the Double NAT issue using a VPN service (like PureVPN) that offers a static and dedicated IP address.
You will have to set up your router to use the dedicated IP address that you use with your VPN. You will need to use this WAN IP address on your router to set up the WAN connection. If done right, you can bypass both the CGNAT restrictions and the Double NAT status.
Frequently Asked Questions
Does your Jazztel Router have CGNAT?
It does. This is because it provides CGNAT-enabled routers to assign IP addresses. By doing so, the Starlink router works with other ISPs.
How can I bypass CGNAT?
The simplest way to bypass CGNAT with Jazztel is to use a VPN service. You use a virtual and dedicated VPN tunnel between your internet-enabled device and a VPN server. You get another ISP address as a result.
Does CGNAT affect online gaming?
Absolutely. Modern online multiplayer games rely on incoming and outgoing connections to host, connect and communicate. CGNAT blocks incoming traffic by default. You must bypass CGNAT for the best online gaming experience, especially when using Jazztel.
