My Synology NAS allows the use of SSL to encrypt traffic. The default certificate supplied works, but gives an exception in the browser: There is a problem with this websites security certificate. The problem is the address and the certificate don’t add up. So the solution is to setup your own domain, link it to your NAS and create a certificate for it.

Register and setup a domain

Registering for a domain is fairly easy. Just come up with a name and check if it is available. Then register it. I’ve used GoDaddy.com but there are more domain registration sites out there.

1. First search for your desired domain name. I live in the Netherlands, so I want a .NL address.
   
2. Hit search and when it’s available click Add to put it in your shopping basket.
   
3. Review your order. I added private registration to mask my information and removed the business registration.
   
   The order total is for the first year. Next years the price will be $21,48.
4. Continue to check out. You will create an account, submit payment information, receive e-mails about your account creation and order. Setting up your domain starts after the payment is completed. Continue to the next step but keep in mind some things may not be there yet because the registration is in progress.
5. Go to “My Account” and setup Free email forwarding for FINDMYNAS.NL. Details are in the godaddy support article Setting up a Forwarding Account in the Email Control Center. You will need this for the next parts.

Note that the used domain FINDMYNAS.NL is not mine and only used for demo purposes because it was available at the time I created this post.
