The NAS Starter Utility discovered my NAS but the status is always unreachable, even
though I can access it.
You may need to add the NAS Starter Utility to your software firewall’s allow list or lower your
software firewall or anti-virus scanner’s security level. Alternatively you may have to configure your
software firewall or other security software to allow UDP port 50127 traffic from the NAS. If there is
a hardware firewall between you and the NAS, configure it to allow UDP port 50127 traffic from the
NAS.
I have at least two NASs in my network, how do I identify which one I want to configure in
the NAS Starter Utility screens.
If you have several NASs connected to your computer/network, give each a unique name. You may
have to disconnect all but one and use the NAS Starter Utility to rename it. Then connect another
NAS and rename it and continue to connect and rename the NASs one-by-one until they are all
connected and each has a unique name.
Alternatively, if you have a DHCP server on your network and you can access it’s list of assigned IP
addresses, you could see which IP address belongs to which NAS. You can check the MAC address
of your NAS by checking the attached sticker in the device housing.

I forgot the server name of the NAS.
• The default server name is ‘NAS’ followed by the number of your model (‘ NAS540 ’ for example).
• Use the NAS Starter Utility to discover your NAS. If you have admin privileges, you can directly
change the IP address of the NAS using the NAS Starter Utility.
• If the server name has changed and you don’t have the NAS Starter Utility, see Section 1.7 on
page 17 to use the RESET button to return to the default setting.
I cannot get to the NAS login screen.
• Use the NAS Starter Utility to discover your NAS. If you have admin privileges, you can directly
change the IP address of the NAS using the NAS Starter Utility.
• Make sure you have used the NAS Starter Utility to initialize your NAS.
• If you used the
RESET button, the NAS may have a new IP address. Close and reopen the NAS
Starter Utility to discover the NAS.
• Make sure the NAS is turned on.
