New router - no contact with Hassio

Im running Hassio on Raspberry pi and my router died.
I have now a new router but I have forgotten witch ports I have to open?
I manage to get in touch with Hassio via Nabu Casa, but not via DuckDns

Need help here please :slight_smile:

The ports you need to open if using DuckDNS would be 443. However, if you are using Nabu Casa, there really isn’t any need for DuckDNS as Nabu Casa does the same thing (without the custom domain name).
