ASMB9 BMC webUI unable to open in local, when MotherBoard connects a single LAN on shared LAN

Due to security reason, Intel disabled OS2BMC. Hence, with only 1 LAN cable connected, shared LAN is unable to ping LAN 1.

Further causes BMC webUI unable to show locally. Please connect another RJ45 cable to shared LAN 2 if you want to access BMC in local network.
