Repro Steps

1. According to the Document(https://learn.microsoft.com/en-us/windows/wsl/wsl-config#main-wsl-settings), to use hostAddressLoopback option, write /Users/{user}/.wslconfig as below.

[wsl2]
networkingMode=true
hostAddressLoopback=true

2. Then hostAddressLoopback does not work.

But it works when wrote as below.

[experimental]
networkingMode=true
hostAddressLoopback=true

I think hostAddressLoopback refers only experimental.networkinMode, not wsl2.networkingMode.

Expected Behavior

hostAddressLoopback works.

Actual Behavior

hostAddressLoopback does not work.

@euxn23 if you look at release 2.0.5 notes (https://github.com/microsoft/WSL/releases/tag/2.0.5) only networkingMode was promoted. hostAddressLoopback is still experimental. Try:

[wsl2]
networkingMode=true

[experimental]
hostAddressLoopback=true

Yeah looks like our docs are incorrect, I'll get that fixed.

"I still have this issue, only when
[experimental]
networkingMode=mirrored
hostAddressLoopback=true
it works."

Crrent state of affairs is that the following works.

[wsl2]
networkingMode=mirrored

[experimental]
hostAddressLoopback=true
