Question:How to use Curtain e-locker to protect NAS through iSCSI?
Answer:Currently most NAS storage servers are running Linux and they do not allow people to install program/software on the NAS. That means we cannot install Curtain Server Plug-in on a NAS storage server, to protect the share folders. Alternatively, we can protect the NAS by mounting it to a Windows server as local virtual disk through iSCSI. Firstly, you need to create iSCSI LUN (logical unit) on the NAS, and then use Windows iSCSI Initiator to create a virtual disk on the Windows server. Finally, you can share the virtual disk and protect it by Curtain e-locker.

P.S. We used Synology DiskStation to demonstrate how to do the setup. The interface and naming will be different if you are using other NAS servers.

Steps to create iSCSI LUN (logical unit) on NAS:
1. In my Synology DiskStation, go to DSM (DiskStation Manager), and click "Main Menu > Storage Manager" as below.

2. In the "Storage Manager" page, select the "iSCSI LUN" item as below. By default, there is no iSCSI LUN in the DSM system.

3. Click the "Create" button, it will pop the setup page. As follow figure:

4. In the "Choose a LUN type", select the "iSCSI LUN(Regular Files)" type, and click the "Next" button. As follow figure:

5. Set up iSCSI LUN properties in this step, we suggest you to set up the "Capacity(GB)" property only, the capacity room is up to you. If you have already set up, click the "Next" button. As follow figure:

6. In this step, you will create a new iSCSI target. Input the "Name" first, we suggest you to enable the CHAP and set up the password. To prevent anonymous use the iSCSI target, please follow figure:

7. Confirm the settings that you have set up, if no problem, click the "Apply" button to create the iSCSI LUN. As follow figure:

8. Now you have created the iSCSI LUN, in the "Storage Manager" page, you can see the iSCSI LUN that you have created. As follow figure:
