I run Docker Desktop (4.15.0) on Windows 10 (10.0.19044) and have encountered the odd problem that when running a Linux-container to communicate with a camera (Basler ace) via Ethernet (GigE), I never receive an image in the container.
Establishing a connection to the camera for configuration and triggering it works fine (both via TCP).
Copying the network traffic also shows that the camera actually sends back packages via UDP, but never get into the container.
Now here’s the odd thing: The exact same container and configuration works on a Linux host though.
The problem is reproducible (tested it on two Windows-PCs with activated and deactivated firewall).

The windows host <PI address host> is addressed and the relevant ports are forwarded to the container.
See the docker-compose file:
version: "3"
services:
basler-camera-service:
container_name: basler-camera
build:
dockerfile: Dockerfile
ports:
- 5001:5000
- 3956:3956 # Basler communication
- 46000:46000 # set Streaming Port to fixed value with pylonViewer
- 5901:5920 # VNC viewer
I spare you the details on the container with the [Basler Pylon](pylon 7.2.1 Camera Software Suite Linux x86 (64 Bit) - Debian Installer Package | Basler installation to communicate with the camera as it obviously works (on Linux). The streaming is set to multicast and the destination port to 46000.
It seems to only occur on Docker for Windows (BTW: it doesn’t matter whether I use Docker Desktop or spin up a virtual machine with Linux and use Docker from there).
