Mirrored mode networking unavailable in Windows 11 Insider build 22635.4880 (and it should be)

[UncleMarky]

Windows Version

Microsoft Windows [Version 10.0.22635.4880]

WSL Version

2.4.10.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.167.4-1

Distro Version

Ubunto 22.04

Other Software

Docker Desktop (Windows), v4.38.0

Repro Steps

Start WSL for the first time since reboot.

Expected Behavior

WSL2 should start with mirrored network mode.

My .wslconfig file contents,

[wsl2]
networkingMode=mirrored

Limits VM memory in WSL 2 - 50% of total memory on Windows or 8GB, whichever is less; on builds before 20175: 80% of your total memory on Windows

memory=8GB

processors=8 # Makes the WSL 2 VM use 8 virtual processors

Sets amount of swap storage space to 8GB, default is 25% of available RAM

swap=8GB

Boolean specifying if ports bound to wildcard or localhost in the WSL 2 VM should be connectable from the host via localhost:port.

localhostForwarding=true

Disables nested virtualization

nestedVirtualization=false

Turns on output console showing contents of dmesg when opening a WSL 2 distro for debugging

debugConsole=false
