wsl: 检测到 localhost 代理配置，但未镜像到 WSL。NAT 模式下的 WSL 不支持 localhost 代理。

[zhaoqiu-china]

Windows Version

Microsoft Windows [版本 10.0.22621.2506]

WSL Version

2.0.9.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

5.15.133.1-1

Distro Version

Ubuntu 22.04

Other Software

No response

Repro Steps

Thanks for your work about wsl.
Firstly, I have tried some updates about "networkingMode=mirrored", but failed. My system version is 22H2 which is not "Release Preview Channel".
So, I delete .wslconfig file.
Finally, when I start new terminal, I see "wsl: 检测到 localhost 代理配置，但未镜像到 WSL。NAT 模式下的 WSL 不支持 localhost 代理。" on the terminal.
The key point is "Release Preview Channel" is requisite for mirrored network in wsl2 ?

Expected Behavior

wsl2 can be visited by other machine in local area network.

Actual Behavior

wsl2 can not be visited by other machine in local area network.

English translation:

wsl: A localhost proxy configuration was detected but not mirrored into WSL. WSL in NAT mode does not support localhost proxies.

I can reproduce this issue.

• Go to Settings > Network & internet > Proxy.
• Turn on Use a Proxy Server
• Set Proxy IP Address: 127.0.0.1 ; Port: 8080
• Launch wsl.exe.

This error message displays every time I type bash or wsl then press enter. It's a bit annoying.
Can we have a config option to turn off this message?

Btw, I'm not using WSL in NAT mode. Here's my .wslconfig:

[wsl2]
networkingMode = bridged
vmSwitch = Bridge
ipv6=true

---

Edit:

Workarounds: Set this config in .wslconfig will suppress the error message:

[experimental]
autoProxy=false

However this config will completely disable the auto proxy feature.

networkingMode=mirrored
dnsTunneling=true

#10650 The problem still occurs in the 2.0.9 version.

networkingMode=mirrored

[mancuoj]

By the way:

.wslconfig
存储在你的 %UserProfile% 目录中。
用于在作为 WSL 2 版本运行的所有已安装的 Linux 发行版中全局配置设置。
只能用于 WSL 2 运行的发行版。 作为 WSL 1 运行的发行版不受此配置的影响，因为它们不作为虚拟机运行。
要访问 %UserProfile% 目录，请在 PowerShell 中使用 cd ~ 访问主目录（通常是用户配置文件 C:\Users<UserName>），或者可以打开 Windows 文件资源管理器并在地址栏中输入 %UserProfile%。 该目录路径应类似于：C:\Users<UserName>.wslconfig。
WSL 将检测这些文件是否存在，读取内容，并在每次启动 WSL 时自动应用配置设置。 如果文件缺失或格式错误（标记格式不正确），则 WSL 将继续正常启动，而不应用配置设置。

If you have set up a proxy before, you also need to delete the code that set up the proxy before. I understand that mirrored has done the same network mapping for the host and virtual machine, and no additional settings are needed. I successfully solved the problem through this method. You can try it

works for me but brought one new problem: my docker engine can't start in WSL2.
if i run a simple docker command then i'll get a The command 'docker' could not be found in this WSL 2 distro.

i just delete the .wslconfig and ignore the warning while starting WSL2...

I started getting flooded with A localhost proxy configuration was detected but not mirrored into WSL. WSL in NAT mode does not support localhost proxies. messages the other day as well. It's not breaking anything but the messages are annoying. I ended up disabling Desktop Notifications for WSL.

[experimental]
autoMemoryReclaim=gradual
networkingMode=NAT
dnsTunneling=true
firewall=true
autoProxy=false

and now the issue is resolved. No warning appears when I start the WSL system, nor does any error come up when I use PyCharm for debugging.

So does the problem matter? It seems that the solution above just shields the error message.

[zhaoqiu-china]

Hi everyone, in the beginning, this issue was created when I failed to taste the mirrored networkingmode. Now I solved this problem and the mirrored networkingmode is ok. The cause of failure is proxy configuration exist in both .bashrc and .zshrc.

[leelesan]

wsl2导致了这个问题，如果配置文件不能生效，可以使用会wsl1版本；

Some of these parameters have been promoted in the latest versions of WSL, so now you can just do:

networkingMode=mirrored
dnsTunneling=true
firewall=true
autoProxy=true

[experimental]
# requires dnsTunneling but are also OPTIONAL
bestEffortDnsParsing=true
useWindowsDnsCache=true

[Jen1us]

[experimental]
autoProxy=false

only this method can solve my issue,THX!!!

If using this wslconfig , you can't use MPI anymore in wsl, may because the firewall stop the communication or something(i dont know)，如果要用MPI别用这个

[experimental]
autoMemoryReclaim=gradual  # gradual  | dropcache | disabled
networkingMode=mirrored
dnsTunneling=true
firewall=true

[Homura59]

其中一些参数已在 WSL 的最新版本中得到提升，因此现在您只需执行以下操作即可：

[wsl2]
networkingMode=mirrored
dnsTunneling=true
firewall=true
autoProxy=true

[experimental]
# requires dnsTunneling but are also OPTIONAL
bestEffortDnsParsing=true
