Win10 PC not protected.

### Is it a bug? - [x] I know this is an issue with the app, and contacting Mullvad support is not relevant. ### I have checked if others have reported this already - [x] I have checked the issue tracker to see if others have reported similar issues. ### Current Behavior I am connected to my win10 pc running the mullvad app via moonlight/sunlight streaming on a linux laptop, using the browser on my win10 pc the mullvad connection checker reports i am not using mullvad and whatsmyip.com reports the same. The browser app is not split tunneled. ### Expected Behavior Mullvad protects my win10 pc even if my linux laptop connects. ### Steps to Reproduce 1. have mullvad app and sunshine running on a win10 pc. 2. connect from a linux laptop running moonlight to the win10 pc. 3. navigate to https://mullvad.net/en/check via librewolf. ### Failure Logs ```shell ``` ### Operating system version Windows 10. ### Mullvad VPN app version 2025.14 ### Additional Information sunshine has upnp enabled but im currently connected via lan and was trying to get internet based connection working when i discovered this.
