Después de instalar y configurar turnerver en un servidor CentOS-7.X, me encuentro con el siguiente problema.
$ ./turnserver
...
...

Este es mi turnserver.confarchivo.
listening-ip=39.39.39.39
listening-port=3478
tls-listening-port=5349
relay-ip=39.39.39.39
external-ip=39.39.39.39
relay-threads=50
lt-cred-mech
userdb=/etc/turnuserdb.conf
# no-stdout-log
log-file=/var/tmp/turnserver.log
pidfile="/var/run/turnserver.pid"
Intento abrir algún puerto, pero no funciona.
$ firewall-cmd --list-ports
3478/tcp 3478/udp
