After I got the web access halfway to work (files are shown, but explorer hangs while downloading) I discovered that WD2go botched my remote router access. The web interface of the browser was accessible before via my domain, now everything is redirected to the MyBook Live.
I need to get my router interface back, I gladly sacrifice the MB Live access for it. I can always get ftp to the router to work.
How can I reroute everything to my router interface when I enter my domain in the browser?
