[Cloudflare Tunnels](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/) can be used to access PiKVM over the internet securely using Cloudflare Zero Trust with the ```cloudflared``` daemon. This is a convenient and free (for private use) tool for allowing access to web services running on your internal network without port forwarding or IPv4/IPv6 compatability issues. This document is provided as an example for accessing your pikvm over the internet but you can also use zerotier/tailscale/insert xyz vpn service here. Basic support like whats shown below is provided as an example, any other setting or functionality needs to be redirected to the appropriate community.

## Prequisites
1. A domain utilizing Cloudflare for DNS
2. A Cloudflare tunnel configured with an application created and secured by an access policy
## Cloudflare Tunnel Steps
1. Login to Cloudflare and provision a tunnel using the steps [here](https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/install-and-setup/tunnel-guide/remote/). Save the tunnel token as we will need this later. In most cases the target will be https://localhost
2. Create a self-hosted application with the url matching one created in the previous step by following the steps [here](https://developers.cloudflare.com/cloudflare-one/applications/configure-apps/self-hosted-apps/).
* You will need to check the http options to disable SSL certificate verification under Tunnels -> Configure -> Public Hostname -> yourapplication.yourdomain -> Edit -> TLS Settings -> No TLS Verify as the PiKVM uses self-signed certificates.

* You will need to check the http options to disable SSL certificate verification under `Tunnels -> Configure -> Public Hostname -> yourapplication.yourdomain -> Edit -> TLS Settings -> No TLS Verify` as the PiKVM uses self-signed certificates.
* Don't skip the access policies as this important to preventing randoms from the internet from gaining access to your PiKVM. Cloudflare offers a variety of login options with the simplest being One-time PINs that are emailed to you. NOTE: This external authentication will not replace the username/password for the PiKVM but instead supplement it acting as a first line of defense from the internet.
## Installation
Unfortunately Cloudflare does not provide binaries for armv7hf so we need to compile from source to generate a working build.
