First, I'm definitely no Linux guru, so "it works" is just about my real only consideration :) Second, this is on a home dev server, which means that security isn't my biggest concern (the server isn't exposed outside my LAN in any way), so I did some things that I wouldn't do on a real, important machine. Don't know why and didn't have the time to investigate. It will change on each reboot of Windows.

That should work fine and make it all completely automatic, but I just haven't done it yet. That's really sort of a different problem -- you can use "localhost" from the host itself, but there's no obvious way to get there from a different machine on the network: WSL2 is running on Windows host A If no distributions are running, you will receive the response: "There are no running distributions." Please allow the WSL 2 networking infrastructure to be configured for bridged mode, as well as the current NAT system.

Negative answer: Not possible in WSL2, you will need to stay with WSL1. netsh interface portproxy does not support port forwaarding of UDP traffic. Since WSL distros dont natively run networking daemons, WSL itself grabs a DHCP address and assigns it to the adapter before your distro starts up. d) Modify Gb NIC and hyperv Interface "WSL" again and enable "bridge" again. As a reminder we didn't intend for users to find and start using this functionality, so please keep in mind that the functionality and experience for this feature can change. I tried it.

There are a few considerations to be aware of when working with networking apps, whether you are accessing a Linux networking app from a Windows app or accessing a Windows networking app from a Linux app, you may need to identify the IP address of the virtual machine you are working with, which will be different than the IP address of your local physical machine. The picture below shows an example of this by connecting to a Node.js server running in Windows via curl. The localhost port actually forward by wslhost.exe on Windows, but it listen on localhost only.. WSLHostPatcher will scan all wslhost.exe processes, then inject . If you haven't ever used Hyper-V start here: https://github.com/luxzg/WSL2-fixes/blob/master/networkingMode%3Dbridged.md#install-hyper-v-features-and-tools, If you already have Hyper-V up and running, start here: https://github.com/luxzg/WSL2-fixes/blob/master/networkingMode%3Dbridged.md#install-wsl-2-preview. The work around is to forward the TCP ports of WSL 2 services to the host OS. Not my repo so I can't guarantee it! Since WSL distros dont natively run networking daemons, WSL itself grabs a DHCP address and assigns it to the adapter before your distro starts up. Pinging WAN IPs was now possible, but no DNS resolution. You can confirm using the command: systemctl list-unit-files --type=service, which will show the status of your services.
