How to use Webdav over the internet

[Storage12AndUp]

I want to know what ports to forward for webdav and do I type the public IP or the private?

Whatever ports you configure. https://www.ixsystems.com/documentation/freenas/11.2-U4.1/services.html#webdav

Public. Or better yet, your domain name (using a dynamic DNS provider if necessary).
