PC can not ping the address allocated by EM7565

IoT Modules MC/EM Series
1

I have a laptop with Windows 10 system. It connects with both ethernet and EM7565. After EM7565 attached successfully, the laptop is allocated with address 192.168.100.55 by EM7565. But, it is not able to ping 192.168.100.55 on this laptop.

However, this laptop has another ip address 10.22.2.21 allocated by the cable ethernet. It is ok to ping 10.22.2.21 on this labtop.

My question is that why it is not ok to ping 192.168.100.55 get from the EM7565.

Hi @steven.shen,
When you connect EM7565 to your laptop, It will create a P2P connection. The module is going to assign Its public IP (192.168.100.55) for your laptop so your laptop access internet. When you tried to ping 192.168.100.55, your laptop used local interface (10.22.2.21) to ping 192.168.100.55. It is not possible
There’re 2 ways to ping 192.168.100.55
#1: Disable local interface
#2: Ping 192.168.100.55 by command
ping 192.168.100.55 -S 192.168.100.55
