I'm running Docker Desktop on Windows 11, and I think I might have inadvertently changed some settings because my containers can no longer access devices on my local network. They can connect to the internet and I can access them from other computers on the network, but it's like a one-way street. I'm wondering if anyone knows of a setting that might be affecting this across all of Docker? I'm suspecting it might be related to how WSL2 networking is configured, but I'm unsure how to troubleshoot that. Any suggestions would be greatly appreciated!

You might want to check the Hyper-V firewall settings. If you want your containers to access devices on your LAN, you may need to open some specific ports there. There's a helpful guide on that if you're unsure.
Have you checked the Docker network settings? Sometimes, tweaking the network configuration in the Docker settings can solve these weird access issues. It's definitely worth exploring if other solutions lead you nowhere.
It sounds like a common issue with WSL2. Basically, all WSL instances can isolate your Docker containers, making direct access tricky. You might want to double-check your network settings to see if Docker is indeed running in its own container environment. That could be where the problem lies.
When I hit a similar issue, I ended up wiping my WSL configuration through Docker Desktop's troubleshooting option. It fixed my connectivity problem, although I lost my containers in the process. Make sure to back up any important data, but it might be worth a shot if you're stuck!
Can you share how you started your containers? If you're using Docker Compose, it could help us figure out the issue. Also, how are you testing the connectivity? Knowing exactly how you can 'ping' or reach the services can give more insights into what might be wrong. Don't forget to check how your networks are set up too!
Sure! I used Docker Compose to set up my services. Right now, I'm able to ping from within the container, and the internet works fine, but I'm struggling to connect to my cameras or MQTT services. I also tried using 'network_mode:host' but that didn't change anything.
Actually, I can connect to the Docker containers from the LAN, so that's not the issue. The real problem is getting the containers to connect back to devices on the LAN.
