-If you'll be fronting with a reverse-proxy that lives on another machine (not on the same one as Matrix), you need to replace `127.0.0.1` in the above configurations with `0.0.0.0` or another network interface.

 For an example where the playbook's Traefik reverse-proxy is fronted by [Nginx](https://nginx.org/) running on the same server, see [Nginx reverse-proxy fronting the playbook's Traefik](../examples/nginx/README.md).
