In Jetson Nano, I want to use the deepstream python apps for object detection based on rtsp live streams as input sources. But Jetson Nano cannot ping my laptop IP, while my laptop can ping jetson nano IP. What is the possible reasons? Is it the firewall of Jetson Nano? They are in the same network, I properly generated rtsp streaming in my laptop. I need to overcome this to go on with deepstream apps with RTSP input. Thanks! ---

No, there is no default firewall. It sounds like the firewall is on your laptop. ---
