If like me you want to host multiple domain names on an ADSL line you will need to use a DDNS service. My chosen one is noip.com
All fine and dandy set the first one up on the Synology NAS GUI to automatically update when your IP changes! Magical it works, but now you want to add a second with the same provider, nope it won’t work, the option for the same provider has gone!
SSH into your NAS
sudo vi /etc/ddns.conf
- Copy the lines that are already there
- Paste directly below
- Change [NoIP.com] to [NoIP2.com]
- Change the domain name
- Connect to Synology NAS and navigate to the DDNS settings
You will now see the second DDNS update in the GUI
