I have a Windows VM that can has an internet connection that acts as a tunnel into a VPN, and this VM is supposed to share this internet connection with the host. This works perfectly in principle: On that Windows VM, I have a network interface named `Outbound` which represents the VPN connection, and an interface named `Gateway` which represents the connection that is shared with the host. I use Windows Internet Connection Sharing (ICS) to provide routing to the `Gateway` interface via `Outbound`. For reasons unknown to me, however, this sometimes just breaks and the only way to get it running again is to simply disable ICS on the `Outbound` interface and re-enable it. Doing this through the UI every time became annoying, so I researched how to do it programmatically. There is [a great superuser answer](https://superuser.com/a/649183/222330) which provides _almost_ all the details you need, but not quite. <a href="https://blag.nullteilerfrei.de/2024/06/26/programmatic-internet-connection-sharing/#more-5917" class="more-link">Do you want to know more?</a>
