WSL: Networking in Mirrored Mode

(2026-07-02)

On machines running Windows 11 22H2 and higher you can set networkingMode=mirrored under [wsl2] in the .wslconfig file to enable mirrored mode networking. Enabling this changes WSL to an entirely new networking architecture which has the goal of 'mirroring' the network interfaces that you have on Windows into Linux, to add new networking features and improve compatibility.

Access from outside:

Run the following command in PowerShell window with admin privileges to Configure Hyper-V firewall settings to allow inbound connections:

Set-NetFirewallHyperVVMSetting -Name '{40E0AC32-46A5-438A-A0B2-2B479E8F2E90}' -DefaultInboundAction Allow

or

New-NetFirewallHyperVRule -Name "MyWebServer" -DisplayName "My Web Server" -Direction Inbound -VMCreatorId '{40E0AC32-46A5-438A-A0B2-2B479E8F2E90}' -Protocol TCP -LocalPorts 80
