I've installed the duckDNS docker container (with TechnoDads Video tutorial. So I guess I got the basic setup right).
Of course I've set up a duckdns account with a subdomain.
However TechnoDad doesn't cover how to access the OMV NAS from outside?
https://[subdomain].duckdns.org doesn't work.
Do I have to make DDNS settings to my router, port forwarding etc.?
