Port Forwarding Error 31526?

Hi Level 2 at wd told me to RMA it.  I don’t have the money to do that.  I’m going to take it back to the store tomorrow, I paid for extra coverage so they better take it back.  I think I might look into something else.  What I don’t know yet.  I mainly bought it not just as a back up, but for the remote web access from my mac as I’m never home.  It did work until that last upgrade. Without all the changing of the router, portforwarding, reservation ip etc.  It’s not the router other devices work and like I said it use to work.  Good Luck to you.
