What is the issue you’re encountering

I am unable to access machines in my AWS VPC network via their private IP address, while using the Cloudflare WARP Tunnel

What steps have you taken to resolve the issue?

Hi, I am trying to use the Cloudflare Tunnel to access a private network on AWS. I have already installed Cloudflare WARP on a machine within this network, disabled “Source / destination checking” for the instance with WARP installed, and on the machine, WARP shows “Status update: Connected”. I have also checked the “Split Tunnels” settings, and lastly, I added a rule to the AWS Security Group for the resources, allowing traffic from the 100.96.0.0/12 network.

In summary, I have an infrastructure on AWS and I need to access some private resources through the Cloudflare Tunnel. Currently, I only want to access them via SSH or HTTP using the private IP address of these resources. Theoretically, accessing http://192.0.1.5 should work, but I haven’t been getting satisfactory results.

For those who have replaced VPN with Cloudflare Tunnel, are there any necessary permissions or configurations for this to work correctly when accessing resources on AWS?

Just supplementing the original post, I emphasize that from the server where Cloudflare WARP is installed, I have access to the HTTP server via curl http://192.0.1.120/

It works!

However, from my local machine:

curl 192.0.1.120

curl : Unable to connect to the remote server At line:1 char:1 + curl 192.0.1.120 + ~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest], WebException + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

As I am validating other posts, my private network does not correspond to any of the networks registered by default in Manage Split Tunnels (exclude).

Include in all EC2 machines a security group with the following rules: TCP protocol, Ports 0-65535 and network 192.0.1.0/24 and network 100.96.0.0/12.

However, there is no communication between my personal machine and the AWS network.
