I have tried and followed all advices and discussions how to enable my Ipad to connect to my WD My Cloud. There are no problems to connect my Ipad and NAS when they’re on the same network - it means my home network. - but it is impossibile to connect from external network. I have tried every type of settings (eg. http://community.wd.com/t5/WD-My-Cloud/HOW-TO-Troubleshooting-Remote-Connectivity-Issues/m-p/617261#M1130) . I have BTHub 3 router.
What else should I take into account?
