The way to do this is via .well-known or an +SRV record. + +#### I have created a .well-known URI. Do I still need an SRV record? + +As of Synapse 0.99, Synapse will first check for the existence of a .well-known +URI and follow any delegation it suggests. It will only then check for the +existence of an SRV record. + +That means that the SRV record will often be redundant. However, you should +remember that there may still be older versions of Synapse in the federation +which do not understand .well-known URIs, so if you removed your SRV record +you would no longer be able to federate with them. + +It is therefore best to leave the SRV record in place for now. Synapse 0.34 and +earlier will follow the SRV record (and not care about the invalid +certificate). Synapse 0.99 and later will follow the .well-known URI, with the +correct certificate chain. + +#### Can I manage my own certificates rather than having Synapse renew certificates itself? + +Yes, you are welcome to manage your certificates yourself. Synapse will only +attempt to obtain certificates from Let's Encrypt if you configure it to do +so.The only requirement is that there is a valid TLS cert present for +federation end points. + +#### Do you still recommend against using a reverse proxy on the federation port? + +We no longer actively recommend against using a reverse proxy. Many admins will +find it easier to direct federation traffic to a reverse proxy and manage their +own TLS certificates, and this is a supported configuration. + +See [reverse_proxy.rst](reverse_proxy.rst) for information on setting up a +reverse proxy. + +#### Do I still need to give my TLS certificates to Synapse if I am using a reverse proxy? + +Practically speaking, this is no longer necessary. + +If you are using a reverse proxy for all of your TLS traffic, then you can set +`no_tls: True` in the Synapse config. In that case, the only reason Synapse +needs the certificate is to populate a legacy `tls_fingerprints` field in the +federation API. This is ignored by Synapse 0.99.0 and later, and the only time +pre-0.99 Synapses will check it is when attempting to fetch the server keys - +and generally this is delegated via `matrix.org`, which will be running a modern +version of Synapse. + +#### Do I need the same certificate for the client and federation port? + +No. There is nothing stopping you from using different certificates, +particularly if you are using a reverse proxy. However, Synapse will use the +same certificate on any ports where TLS is configured. + ## Troubleshooting You can use the [federation tester]( diff --git a/docs/postgres.rst b/docs/postgres.rst
