  4. Run the tracert command to trace the IP address of the LAN port of the device, and check whether packets can reach the LAN port of the NGAF device.
  5. Connect a computer to the MANAGE port (the eth0 port by default) through the network cable, and set the IP address of the computer to the 10.251.251.0/24 network segment. Then test whether the default IP address (10.251.251.251) of the MANAGE port is accessible.
  6. Change the browser to repeat Step 5.
  7. If you still fail to log in to the device, contact the technical support engineer from Sangfor in time.
