Web Station
You can enable Web Station via this menu, which, in short, allows you to create a website that is hosted entirely on your Synology NAS. Built-in PHP and MySQL support makes creating dynamic, database-driven websites for your business possible. The NAS only has minimal energy requirements, so you won't have to worry about inadvertently increasing the electricity bill by hooking it up to a steady, fast, and reliable Internet connection; the DS215+ can handle the workload of a light webpage. You can configure various PHP setting once you enable Web Station.
Terminal & SNMP
Terminal and SNMP options allow you to log into your Synology NAS via Telnet and SSH command-line interface services, and you can monitor the server's network flow through the appropriate managerial software.
