Remote Access Issues - Connection failed (31520)

I just bought and trying to setup MY BOOK LIVE as a home server.  My network is made up of a modem which is then connected to a Wireless Router. So MBL is now cabled connected to Wireless Router.  I am able to tranfers file to and from between my computer and MBL.  The only problem starts when I am trying to set up remote access for my iPad and iPhone.  I believe the the problem lies on the failure of connection:

Anyone has solution to resolve the connection failure issue? How do i make the connection more stable? Or is it caused by the way I set up my network described above?

Many Thanks. Cheers!!

It sounds like your MBL is not connecting to the Internet, you may try bypassing the router and plug the MBL directly to your modem.
