• WSL 2
• WSL 1

Kernel Version

Repro Steps

Connect to the corporate in the office (which does NOT requires the usage of VPN) and WSL2 does not have internet.

The .wslconfig located at "C:\Users\myusername.wslconfig" is as below

# Settings apply across all Linux distros running on WSL 2
[wsl2]

# Limits VM memory to use no more than 4 GB, this can be set as whole numbers using GB or MB
memory=4GB

# Sets amount of swap storage space to 8GB, default is 25% of available RAM
swap=2GB

# If the value is mirrored then this turns on mirrored networking mode.
networkingMode=mirrored

# Enforces WSL to use Windows’ HTTP proxy information
autoProxy=true

# Setting this to true allows the Windows Firewall rules, as well as rules specific to Hyper-V traffic, to filter WSL network traffic.
firewall=false


[experimental]
autoMemoryReclaim=dropcache

I have environment variables set as follows for proxies (just representative URLs, not actual)

http_proxy
http://rb-proxy-rst.brd.com:8080

https_proxy
http://rb-proxy-rst.brd.com:8080

The wsl,conf file in WSL at /etc/wsl.conf is as below
``
[user]
default=myusername

[interop]
enabled=true
appendWindowsPath=true

[network]
generateResolvConf = false

[boot]
systemd=true

The `resolv,conf` file in WSL at `/etc/resolv.conf` is as below

nameserver 10.187.250.203
nameserver 10.171.121.11

### Expected Behavior

WSL2 should connect to the internet even in office but it does not when testing the connection with curl, I get the error "curl: (22) The requested URL returned error: 407"

### Actual Behavior

WSL2 connects to the internet when working behind a proxy (using Cisco AnyConnect) without any changes to the above mentioned settings.

### Diagnostic Logs

My computer prevents me from opening Feedback Hub & due to lack of rights I am unable to install WPR as well.

Then I tried to collect the log using WPR & below is the message when I try to run Invoke-WebRequest -UseBasicParsing "https://raw.githubusercontent.com/microsoft/WSL/master/diagnostics/collect-networking-logs.ps1" -OutFile collect-networking-logs.ps1

I have tried all of these methods and provided the outputs that I am getting.
Unfortunately all the methods are running into errors
