How to Avoid Jazztel CGNAT in Spain

Are you a Jazztel user facing challenges with tasks like hosting personal game servers or accessing your desktop remotely? These problems could occur due to Jazztel’s use of Carrier-Grade NAT (aka CGNAT).

CGNAT allows multiple users to share a single public IP, which helps to conserve IPv4 addresses. However, this can create hurdles with direct connections to your network, affecting activities like VoIP calls, online gaming, and more.

If you are tired of these disruptions and looking for a reliable solution, we have got your back. In this guide, we will show you how to avoid Jazztel’s CGNAT with the help of a port forwarding VPN like PureVPN.

What Issues Does Jazztel CGNAT Cause?

Jazztel’s implementation of CGNAT can result in the following issues for users:

Server Hosting Challenges

Trying to host a personal server for purposes like file sharing, streaming, or gaming? CGNAT is bound to make things difficult as it blocks incoming connections to your server. The result: you will not be able to connect to your server from outside your network!

Gaming Connectivity Problems

If you are into gaming, CGNAT can be a pain. It disrupts peer-to-peer connections in online games, hindering direct communication between players. This causes frustrating problems such as lag, disconnects, and difficulty joining game servers.

Remote Access Roadblocks

CGNAT makes remote access to your home network a hassle. Accessing files, controlling smart devices, or checking security cameras becomes close to impossible because CGNAT does not allow direct connections to your specific device.

VoIP Setup Challenges

If you use VoIP services to conduct business or stay in touch with friends and family, CGNAT can make your life difficult. It blocks the ports needed for VoIP communication, resulting in poor audio quality, setup complications, and dropped calls.

How to Check if Jazztel Uses CGNAT

Here is how Jazztel users can determine if their connection is under CGNAT:

Method 1: Check the Router’s WAN IP Address

Open a web browser and enter your router’s IP address into the address bar.
Enter your username and password to access the dashboard.
Navigate to the status screen on the dashboard.
Find the section labeled as ‘WAN IP’ or a similar term, which might vary based on the router model.
Examine the IP address assigned to the router’s WAN interface.
If this IP address falls within the range of 100.64.0.1 to 100.127.255.254, your connection is likely behind CGNAT. This IP range is designated for CGNAT usage.

Method 2: Compare WAN IP and Public IP Address

Follow the steps from Method 1 to find and note down the WAN IP address from your router’s dashboard.
Open a new tab in your web browser
Search for “what is my IP address” and press Enter.
Remember the public IP address displayed by the search results.
If the WAN IP and the public IP address are different, it indicates that your ISP is using CGNAT.
If they match, your connection likely has a direct public IP address, meaning it is not behind CGNAT.
