# Warp CloudFlare Tunnel on Mac

## Setup Warp on MAC to tunnel using cloudflare DNS : 1.1.1.1

### Steps
- Download WireGaurd from Mac app store
- Add a new empty tunnel in the app. let the window remain open after it generates a public and private key.
- Follow next steps
- copy following code and paste it on a python online compiler. I'm using https://repl.it/languages/python3 to compile. This src code was taken from https://raw.githubusercontent.com/554923619/cloudflare-warp-wireguard-client/master/wgcf.py

- Make sure to run newer code.

- Run the program and accept the terms of cloud flare
- copy the private key and public from wire gaurd from previous steps and paste it in the python app when required.

- 2 files will be created in online repl. save them at your mac safe.

- from the .conf file, select all text and replace it with wiregaurd private key area text
- save with name Cloudflare Warp
- Save and Activate
