Advanced Suggestions
• Try to access the NBG-460N using another service, such as Telnet. If you can
access the NBG-460N, check the remote management settings and firewall rules
to find out why the NBG-460N does not respond to HTTP.
• If your computer is connected to the WAN port or is connected wirelessly, use a
computer that is connected to a LAN/ETHERNET port.
