Iomega drive

I have a n Imac Lion OSX An airport Extreme, several USB External hard drives as well as an Iomega NEtwork Drive connect to the Extreme.

Up until a short while back I could access the Iomega via typing in the IP addres and then Safari would open the Iomega screen so I could add or manipulate files etc, Now the extreme does not open siad web pageand it will only allow Me to access the Files on the Iomega via "Finder" alsothere is a new screen when I open the Airport Utility

What has changed and can anyone advise me how I can get theIomega browser window back in Safari?

Thanks
