Secure your Synology NAS, install a SSL certificate

Home Lab
154 Comments

I’ve been using the default setup on my Synology DS412+ with HTTPS enabled for a while now but knew it really wasn’t all that secure without a proper SSL certificate and creating a self-signed certificated isn’t all the much better and can be easily forged. I decided it was about time I used a “real” certificate to better secure the NAS.

Prerequisites before starting

  • You need to own a domain name, for example MikeTabor.com and be able to receive email from the domain name.
    If you don’t already have a webhost for the domain, I’d suggest BlueHost.

  • You also need a DDNS service setup. In this case and for my use, I simply use the Synology DDNS service they offer for free.
  • With those two setup, you will also want to add a CNAME DNS forward from your domain (or subdomain if you wish to go that route) to your DDNS service.
  • Finally you’ll want to make sure Port Forwarding has been configured on your router.

Setup Synology Syslog server for VMware ESXi

After performing my home lab upgrade, ESXi now runs from a USB stick and because of that vSphere would complain that the system logs where on non-persistent storage:

ESXi syslog error

If I wanted I could have ran the vCenter Server Appliance (vCSA) as it comes with it’s own syslog server, or I could have used something like KIWI or Splunk to be my syslog server. I instead went the route of my Synology NAS as it too has the ability to act as a syslog server and these are the steps I performed to setting it up.

VMware ESXi 5 home lab upgrade

In the past I’ve been using a single server to run my VMware ESXi home lab. it was slow, old, big and loud. I’ve been meaning to upgrade my home lab for a while and just never got around to it, until now! When looking for new hardware I wanted the servers to be as compact as possible, quiet, and low energy usage as possible while still having some horsepower.

I debated on going the whitebox solution as I build all my own desktops anyway, I also looked at several other solutions such as the HP ML310e server, Shuttle XH61V barebones machine, but ultimately decided to go with two Intel NUC i5’s.

Intel NUC i5 and 16GB ram

Intel NUC i5 DC53427HYE Features:

  • Uses very little energy
  • Completely quiet
  • Supports up to 16GB RAM
  • A dual core CPU that scores nearly 3,600 in PassMark benchmarking
  • Includes vPro which allows me to easily run both NUC’s headless
  • Extremely small, nearly 4 1/2″ inch square footprint

How to create a virtual machine on a Synology NAS

A common request I’ve seen among Synology NAS owners, is the ability to run virtual machines directly from their NAS. Recently Synology released a beta version of their new Virtual Machine Manager package that allows users to do exactly that.

Below I’ll detail how to install, configure, and create a Windows 10 virtual machine on my Synology DS1815+.

Before getting started, your Synology NAS not only needs to be compatible but also needs to meet a couple requirements:

You’ll also want to have a couple ISO images downloaded and ready; Windows 10, Synology Guest Tools, and Windows Virtio Drivers.

With that, lets get started!
