Configurazione dispositivi Mikrotik
La configurazione di dispositivi Mikrotik può essere effettuata in due varianti:
- Mikrotik con checkip: Configurazione di Industrial DNS classica con verifica del cambio dell’IP su servizio esterno. Non genera aggiornamenti illeciti.
- Mikrotik senza checkip: Configurazione di Industrial DNS su Mikrotik quando l’IP pubblico è assegnato direttamente alla porta esterna e non cambia. Da chiamarsi una sola volta.

}
Lo script deve essere eseguito dallo scheduler una volta al minuto per verificare il cambio IP.
/system scheduler add name=dynDNSit interval=00:01 on-event="/system script run dynDnsIT\r\n"
