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 management UI through port 5000.
Ports used for HTTPS connection:
 DSM: The port number is 5001, so you can access the management UI 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/
 Photo Station: The port number is 81, so you can access Photo Station through the secure channel:
https://Synology_Server_IP:81/photo/ or https://Synology_Server_Name:81/photo/
About importing certificate:
If you have a certificate issued by the trusted Certificate Authority (CA), please click Import Certificate to
upload your own certificate and private key in order to host a valid SSL server. The certificate should match the
private key. Please keep your private key safely.
Security
Click the Security tab to modify the security level for each DSM browsing session.
To set the logout timer:
1 Enter any value between 1 to 65535 in Logout timer (minutes) to specify the idle time period before the
automatic logout.
2 Click OK.
An automatic logout occurs if you are inactive for the specified time period.
To skip IP checking:
1 Tick Enhance browser compatibility by skipping IP checking.
2 Click OK.
If you access DiskStation through a HTTP proxy and encounter random logouts, you can skip IP checking to
avoid this problem. Nonetheless, skipping IP checking will lower the security level.
