Hyper-V VMs (and WSL 2) Unable to Bridge Internet

Greetings All,

This has been killing me for a few weeks now.

Windows 10 Pro, everything working well from Windows.

However, after installing the Hyper-V toolchain and cremating a new VM, I’m unable to access outgoing internet in the guest VM (internet from the host remains fully functional).

The same thing happens with WSL 2 installs. I’ll download Ubuntu 20.04 LTS, from the MS Store, for instance. Ubuntu loads fine, but no outbound traffic. I can’t sudo apt update or even ping google.com (100% packet loss).

I’m sure I’ve muffed up the Virtual Switches or the NAT or whatever that Hyper-V is using but I don’t know how to tell nor can I figure out how to fix it (either I’m finding the wrong tutorials or I’m effing them up when following them).

Anyone have links to some good resources to get this all up and running.

I have tried uninstalling / reinstalling Hyper-V with Windows Add or Remove Features. I have also tried the network reset. But I’m not 100% sure I did it right.

Thanks in advance for your time!
