After applying the port forwarding, you can go tohttp://www.portchecktool.com/ to check that the ports are open. In my experience, I was only able to see that port 1723 was open;all the others resulted in the port check tool reporting a “Connection refused” error. A connection refused error means that either there are no services configured to listen to that port or that a firewall is blocking them.I spent many hours debugging, but could not find where the issue was. My Windows laptop connected via PPTP and my Android phone was able to connect via L2TP/IPsec, so I know that the NAS was configured to listen to the ports and that the router properly forwarded them. Since I could establish the connections though, which is the end goal, I stopped trying to figure out what caused the connection refused errors. If this continues to be a problemfor you, I would suggest temporarily disablingany firewalls on your router.

My phone, at the time of this writing, was running Android 4.4.4. With Android, you don’t need to download any third party VPN apps to be able to connect. Simply open up Settings Connections More networks VPN. Then select “Advanced IPsec VPN”. Enter the public IP of your router (http://www.portchecktool.com/ will tell you what the IP is, as long as you are browsing on the same network as the router) and the preshared key that you selected above. You will be prompted to enter the username and password when you connect. For convenience, you can tap on the entry for the connection you just created and select “Create shortcut” to put the connection on your home screen.

I understand your point, but since my initial question were not "how should I do my companies backups" I have not detailed how our current backup solution is designed. We already have a high-performance Cloud provider for all business critical stuff with real-time replication in addition to 45 days data retention (in two sequences). This backup I do at home on the QNAP is only for some IT stuffs that we don't want to pay for high performance Cloud storage but that we don't want to loose in the case of a disaster.

Hey Sir Richie, Thank you for this great guidelines. Anyways, I’ve followed every step and I had it working but after a while I’ve got disconnected. My connection only last for less than a minute. I’ve managed to setup my QNAP and PEPLINK.

As a bonus for Windows users, you can head over to the and download myQNAPcloud Connect, which is a desktop application that makes setting up VPN easier and, after connecting, provides a GUI where you can launch NAS apps like File Station, browse network folders on the NAS, and map network drives. myQNAPcloud Connect saves the VPN connections to Windows, so you would see them just as if you had set them up via Windows itself.

At this point, you might ask why I didn’t just disable PPTP if it was less secure. The reason was that I found that I could only VPN into the NAS using PPTP on Windows when I’m outside of the local network. On the local network, Windows was able to connect with L2TP/IPsec.

Update 7/14/2018: A reader referred me to this article which may assist more in setting up connections with Windows 10:

Recently we've acquired a QNAP TS-453A NAS system for storing our larger datasets. This does offer quite a few other nifty tricks though, such as the relatively easy configuration of a VPN. However it does take a few tricks to get this working properly in Windows 10. We will be using a L2TP/IPSec connection. There are other options in the QNAP VPN app: PPTP and OpenVPN. PPTP is considered insecure nowadays, while OpenVPN should be even more secure than L2TP/IPSec. However we did chose the latter because it is more easily supported by different kinds of devices.

I just checked for a business hardware VPN router to handle all the routing in my setup, but the MAJOR (very major) problem is the VPN tunnel throughput on any router. For example, a 650$ Cisco VPN router will only offer like 150 Mbps of IPSec VPN Tunnel throughput which is a MAJOR decrease over the actual speed and capacity of the QNAP VPN client... I think the reason is because my QNAP have a large CPU with quads or even eight cores to handle the VPN tunnelling because I have no problem reaching 300+ Mbps through the tunnel. So I can't imagine working with a 150 Mbps capacity later...

Are you sure it's impossible to do that? Because when I look at my QNAP I see all the server's services such as DHCP Server, DNS Server, VPN Server, etc. I am just not sure how to setup this in accordance to my home network.
