What if your server only supports IPV6 but you need to serve traffic to IPV4 users?

By Digv | Date: September 22, 2023

With the transition to IPv6 becoming increasingly important due to the exhaustion of available IPv4 addresses, you may find yourself dealing with situations where you need to route IPv6-only traffic to IPv4. This can be especially relevant in hybrid network setups or during the gradual IPv6 adoption process. In this article, we will explore how to use Cloudflare Tunnel, formerly known as Argo Tunnel, to achieve this goal effectively.

 

 

Prerequisites:

 

Before we dive into the tutorial, ensure you have the following prerequisites in place:

 

1. A Cloudflare account: Sign up at https://www.cloudflare.com/ if you don't have one already.

 

  1. 2. Cloudflare Tunnel installed: Install the Cloudflare Tunnel software on the server where you want to route traffic from IPv6 to IPv4. You can download it from the Cloudflare dashboard.

 

 

Step-by-Step Guide:

1. Configure Cloudflare Tunnel:

  1. Log in to your Cloudflare account.

  2. In the Cloudflare dashboard, go to the "Tunnels" section.
