I have installed WSL2 on my corporate laptop (Windows 10 Enterprise version 1909). When my laptop is on a corporate VPN (Global Protect) with full tunneling, I lose network connectivity from the WSL2. I cannot do DNS lookup and also I cannot cURL to any website.
Everything works fine when my host laptop is off a VPN.
Note: WSL2 is using Hyper-V with Internal virtual switch.
