The probliem is that my network has no DHCP. In an other network with DHCP there is no problem to see the NAS but there is no posibility to configure a static IP, I was searching but I cannot find any posiblity to configure a static IP. I know the ip adress in a network with dhcp but when I try to open this ip in a browser I only can see an error page, WTF!!! Does anybody knows how to configure a static IP for a Home Duo?
