Portmaster blocks windows sandbox internet connection #1324

Greetings and welcome to our community! As this is the first issue you opened here, we wanted to share some useful infos with you:

VMs are out of scope at the moment, and I guess that windows sandbox is a vm type system. If you want to run a VM to test software which I consider a good idea! then I can recommend https://www.virtualbox.org/ |

Hey @wewlad-dev, thank you for reporting on a compatibility. We keep a list of compatible software and user provided guides for improving compatibility in the wiki - please have a look there. If you have managed to establish compatibility with an application, please share your findings here. This will greatly help other users encountering the same issues. |

@Raphty Answering your question, yes, Windows Sandbox is a virtual machine in concept, however, unlike Vmware/VirtBox, it's more suited to test non-persistent programs without the need to reinstall/snapshot the guest OS, just as the name imply, rather a sandbox to test some unknown software, it also somehow better at not being detected as VM by some programs that will not run if they are inside a VM (some rootkits, etc.) |

Thanks for the clarification, and tbh I had no idea that is a thing, that is a cool option. But as I said, VMs are not all compatible atm. We are planning a VM mode where we handle the network traffic from VM software differently, but again that is planned, and as of now there are only some VM Software that work. I am sorry but windows sandbox might be incompatible atm, if you find a workaround let the people know here, and I will add a guide to the wiki like this one https://wiki.safing.io/en/Portmaster/App/Compatibility/VM/HyperV or that https://wiki.safing.io/en/Portmaster/App/Compatibility/VM/KVM (maybe they help as well) |

It is also preventing Windows Defender Application Guard to work ? i can't get connection! 😭 😭 |
|
I cannot use Windows Sandbox if Portmaster is active I already tried the workaround for Hyper-V Compatibility (as the Wiki suggest):
and also static DNS but both doesent work |
|
@Raphty i really would like to support portmaster with a PRO subscription. As I am developing software VM support (Hyper-V, VirtualBox, Windows Sandbox, Docker) is crucial for me. For the time beeing this is a blocker moving to portmaster from GlassWire |
|
well i got network in sandbox working now despite of having issues with it previously, look like you just need to allow traffic for Windows Service: Shared Access not sure why i had issues with it previously, but i still can't get WDAG to work 😢 there is no traffic visible in the ui |
|
In my case, only DNS stopped working. I got it to work be entering the routers IP as DNS in the network settings. Ping did work before. |
What did you expect to happen?:
Portmaster on host windows blocks guest windows sandbox internet connection
How did you reproduce it?:
Have Portmaster running on the Host windows, turn on Windows Sandbox to have a guest windows running, the guest OS will have no internet connection, if you quite Portmaster from the tray icon, the internet gets back to work inside the guest windows.
