Hi!
How can i connect to my WDMyCloud drive from my iPhone with Infuse 4 Pro App?
I have a static IP from my ISP.
Should i use SMB, WebDAV, WebDAV (HTTPS), FTP or SFTP?
Which port(s) do i need to open on my router?
Grateful for any help 
FTP/SFTP or WebDAV will be your best choices for remote streaming.
Standard ports are below.
FTP - 21
SFTP - 22
WebDAV - 80
WebDAV (HTTPS) - 443
Thank you!
TCP or UDP or TCP/UDP?
TCP, I think.
