Which ports enable?

is there any specific port on my router that should be opened in portforwarding for my wd mycloud?

It depends on what you’re trying to do.

hoping to fix my remote access problem “cannot access device(0)”

When you select manual cloud access configuration, the Cloud tells you what ports to configure.

if i am right says : 80 & 443. but these two portw are very important for my security according to my ISP.

Although they are important i enabled them and then i had no wifi access in my house from any of my devices (smartphone - tablet)

Then pick whatever ports you want.
