The turnserver will also chose a port dynamicly when a new call start. The is between 49152 - 49192.
The turnserver will also chose a port dynamicly when a new call start. The is between 49153 - 49193.
To have a fully functional turnserver you need to open these ports (if it is not automatically done) on your ISP box.
For some security reason the ports range (49153 - 49193) isn't automatically open by default. If you want to use the synapse server for voip or conferencing you will need to open this port range manually. To do this just run this command :
To prevent the situation when the server is behind a NAT, the public IP is written in the turnserver config. By this the turnserver can send his real public IP to the client. For more information see [the coturn example config file](https://github.com/coturn/coturn/blob/master/examples/etc/turnserver.conf#L102-L120). So if you IP change the turnserver config might be obsolete. To fix that you just need to upgrade the app manually. By this the config will be automatically fixed.
```
yunohost firewall allow Both 49153:49193

For more information see [the coturn example config file](https://github.com/coturn/coturn/blob/master/examples/etc/turnserver.conf#L102-L120). So if your IP change you could run the script `/opt/yunohost/__SYNAPSE_INSTANCE_NAME__/Coturn_config_rotate.sh` to update your config.
If you have a dynamic ip adresse you also might need to update this config automatically. To do that just edit a file named : `/etc/cron.d/coturn_config_rotate` and add the fooling contenant (just adapt the __SYNAPSE_INSTANCE_NAME__ which could be `synapse` or mybe `synapse__1`).
```
*/15 * * * * root bash /opt/yunohost/__SYNAPSE_INSTANCE_NAME__/Coturn_config_rotate.sh;
