# Enable TLS

There are two ways to configure the Relay Proxy to accept HTTPS requests:

* **External TLS (recommended)**

  The recommended way to connect to the Relay Proxy using TLS is to place a reverse proxy, such as nginx, in front of the Relay Proxy. Then all connected SDKs must make requests to the reverse proxy URL instead of hitting the Relay Proxy directly.

  A sample docker compose for this architecture is included in this [examples folder](https://github.com/harness/ff-proxy/tree/main/examples/tls_reverse_proxy) in GitHub.
* **Native TLS**

  You can configure the Relay Proxy to start with HTTPS enabled. This can be configured using the [TLS configuration options](/feature-flags/use-feature-flags/use-ff/relay-proxy/configuration.md#tls).

  This does not provide every fine-grained configuration option available to secure servers. If you require more control, the best option is to use a program made for this purpose, and use the **External TLS** option.
