Start by going to the livechat plugin settings of your instance, then enable the setting "Enable connection to room using external XMPP accounts".By checking this setting, new settings appear below.
First of all, the "Prosody server to server port" field.This one defaults to 5269, which is the standard port for this service.You can however change to another port, if this is already in use on your server.
Next, the field "Server to server network interfaces" field allows you to specify which network interfaces the server should listen on.The default value "*, ::" indicates to listen on all IP addresses.You can change these values, if you wish to listen on only certain IP addresses.The syntax is explained next to the setting.
For the "Certificate folder" setting, you can leave it empty.In this case, the plugin will automatically generate self-signed certificates.Some XMPP servers may refuse to connect, depending on their configuration.In this case, you can indicate here a path on the server, in which you must place certificates to be used by the module.It is up to you to generate and renew them.See bellow for more information.
If you are using Docker for your Peertube, you need to modify the `docker-compose.yml` file to open port 5269 of the `peertube` container, so that the outer world can connect to it.
Once you have chosen a task list, a new task will be created. To see the task, open the task application using the top menu. More information in the livechat plugin documentation.
You need to add [DNS records](https://prosody.im/doc/dns) allowing remote servers to find "room.your_instance.tld" and "external.your_instance.tld" components.
