Windows 10: Completely reset wsl, including network configuration

Hi,I'm currently using an Insider build. 22458However, I had this problem a few times on other builds. and wsl worked beforeWhen I start wsl, I'm not able to do a DNS request. Pinging an IP address directly works.I tracked this problem down to the file: /etc/resolv.confIt includes the DNS server address.The default is: 172.22.192.1However, this doesn't work.If I change it to 1.1.1.1 Cloud Flare DNS it works again.However, after every restart of wsl it changes it back to the default.There is a file called wsl.conf in which I can disable generating this file, but if always just deletes

How to configure WSL Ubuntu (or any WSL distro) to use a NAT virtual network

I've installed WSL Ubuntu on my Windows 10 laptop and it is running fine.

However, it is not able to access anything on the Internet at port 80 and so forth. I cannot use apt package installer to install any software at all.

My host laptop Windows environment has no problem, of course, with Internet access.

Info I've gleaned is that WSL is being blocked by a firewall. Am using Kaspersky as mandated by internal corporate policy. I've added an exception rule for WSL but that has no positive effect on the problem. Additional info I've gleaned is that others have
had same experience - unfortunately this doesn't allow programs running in WSL virtualization any access out to the public Internet.

The latest info I could find is that WSL just flat out won't work with several prominent Windows firewall apps unless they are disabled of even uninstalled (not a possible option for me).

So I followed these instructions and created a NAT virtual network:
Set up a NAT network

Got that created with no problem and it shows up as eth3 interface on my laptop.

Remaining instructions at the above link talk about how to get Docker for Windows and other Hyper-V VMs to use this NAT. However, I can't find anything that instructs how to setup WSL to do so. WSL evidently can't be managed in same manner as other Hyper-V
VMs.

Presumably the iptables or ip command to setup routing could be used to do this in the Ubuntu Linux environment, but that is where am appealing for help from anyone that knows how to do this in respect to WSL.
