Hello,
I succeed to use WD Cloud application remotely 
What is now missing is the possibility to do backup remotely with MBL, for this I have to solve following issue:
When connecting via wd2go site outside my lan, just after “View my shares”, I can see shares(3) but I cannot see those shares and I get following message:
ClassNotFoundException
com.wd.nas4g.mapdrive.MapDrive.class:cry:
I found the following in forum:
