I have a Synology NAS that I am hosting 3 domains on. DriverNas.com is the main domain for the NAS and SchoonerNAS is for mail and Mike-Fran.com is for a website. Synology only allows one DDNS to be updated for each DNS host so I can only have one domain updated with DYNU. I tried a CName record but it doesn't allow @. Grouping didn't work for me either. How can I get the 3 domains to all have the same DDNS IP? Thanks.
