## Adjusting SSL in your server
You can adjust how the SSL is served by the nginx server by setting the `matrix_nginx_proxy_ssl_preset`. This is based on the Mozilla Server Side TLS
Recommended configurations. It changes the TLS Protocol, the SSL Cipher Suites and the `ssl_prefer_server_ciphers` variable of nginx.
The posible values are:
You can adjust how the SSL is served by the nginx server using the `matrix_nginx_proxy_ssl_preset` variable. We support a few presets, based on the Mozilla Server Side TLS
Recommended configurations. These presets influence the TLS Protocol, the SSL Cipher Suites and the `ssl_prefer_server_ciphers` variable of nginx.
Possible values are:
- "modern" - For Modern clients that support TLS 1.3, with no need for backwards compatibility
- "intermediate" - Recommended configuration for a general-purpose server
- "old" - Services accessed by very old clients or libraries, such as Internet Explorer 8 (Windows XP), Java 6, or OpenSSL 0.9.8
- `"modern"` - For Modern clients that support TLS 1.3, with no need for backwards compatibility
- `"intermediate"` (**default**) - Recommended configuration for a general-purpose server
- `"old"` - Services accessed by very old clients or libraries, such as Internet Explorer 8 (Windows XP), Java 6, or OpenSSL 0.9.8
The default is set to `"intermediate"`.
**Be really carefull when setting it to `"modern"`**. This could break comunication with other Matrix servers, limiting your federation posibilities. The
[Federarion tester](https://federationtester.matrix.org/) also won't work.

If you want to override one of the values used by the preset, you can use this three variables:
Besides changing the preset (`matrix_nginx_proxy_ssl_preset`), you can also directly override these 3 variables:
- `matrix_nginx_proxy_ssl_protocols`: for specifying the supported TLS protocols.
- `matrix_nginx_proxy_ssl_prefer_server_ciphers`: for specifying if the server or the client choice when negociating the chipher. It can set to "on" or "off".
- `matrix_nginx_proxy_ssl_prefer_server_ciphers`: for specifying if the server or the client choice when negotiating the cipher. It can set to `on` or `off`.
- `matrix_nginx_proxy_ssl_ciphers`: for specifying the SSL Cipher suites used by nginx.
