Yep…zemun2’s suggestion is the best. To get access to your files on EX4 from a computer from outside the network, ftp is the best method.
You will need an ftp client software installed on the computer that you need access from. FileZilla is an excellent free client for PCs and Macs. Also, you will need to do port forwarding from your router to your EX2. This in addition to setting up ftp on EX2 through the dashboard.
BTW, another alternate way (but only for the admin of EX2) to access the files would be to use the dashboard’s Web File Viewer (available under Apps). I have also seen somebody post a way to do that not only for admin but ANY USER setup for access but it requires a couple steps for the initial access. And for this to work, you will need to enable remote dashboard access. I have not tried it personally so I can’t comment on whether it works or not but here is the post where someone else tried it and detailed the process → http://community.wd.com/t5/WD-My-Cloud-EX2/Web-Access-using-browser-only/m-p/713316#M226
I personally prefer the ftp method but if you cannot install additional software on the computer you need access from, the alternate method might be the solution albeit a bit more fussy method.
