HTTP Service
Click the HTTP Service tab to change the port number for accessing DSM or configure HTTPS settings. When
the HTTPS connection function is enabled, any connection to Synology DiskStation via the HTTPS protocol will
be encrypted with the SSL/TLS encrypting mechanism.
More Information
About redirecting to HTTPS connection:
When the option Automatically redirect HTTP connections to HTTPS is checked, you will be redirected to
port 5001 while trying to access the web DSM through port 5000.
Ports used for HTTPS connection:
 DSM: The port number is 5001, so you can access the DSM through the secure channel:
https://Synology_Server_IP:5001/
 Web Station: The port number is 443, so you can access Web Station through the secure channel:
https://Synology_Server_IP:443/ or https://Synology_Server_Name:443/
Security
Click the Security tab to modify the security settings for each DSM login session. The following options are
available here:
 Logout timer: An automatic logout occurs if you are inactive for the time period you specified in the logout
timer.
 Enhance browser compatibility by skipping IP checking: If you access DiskStation through a HTTP proxy
and encounter random logouts, you can skip IP checking. However, skipping IP checking will lower the security
level.
Router Port
Click the Router Port tab to configure router port settings. To open files on the DiskStation with Internet services
(such as Google Docs or Pixlr Editor), please enter the hostname or public static IP address of the DiskStation,
as well as the public port number. These settings only need to be modified if different port numbers were
specified for the router port (assigned on your router) and the local port (assigned on your DiskStation) during
setup.
Certificate
A certificate can be used for SSL secured services of the DiskStation, such as web, mail, or FTP. Having a
certificate allows users to validate the identity of a server and the administrator before sending any confidential
information. Click the Certificate tab to manage and view the status of DiskStation certificates, allowing you to
create, import/export, or renew certificates. The certificate setup wizard helps create self-signed certificates or
download certificate signing requests (CSR) for registration with certificate authorities (CA).
For more information regarding managing certificates, please see DSM Help.
