As in title, I want to make Ubuntu 20.04 LTS WSL use proxied connections; I am in China, behind the infamous Great Firewall of China, if that doesn't ring any bells, just Google it.
Fortunately I know how to bypass it freely(as in "free of charge"), currently I use Lantern, its http proxy port is 1053, I had set it to "manage system proxy" and "proxy all traffic", I had run these commands:
netsh winhttp set proxy 127.0.0.1:1053 reg add "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /t REG_SZ /d "127.0.0.1:1053" /f
And made Lantern proxy PowerShell traffic in addition to browsers and downloaders.
Now, I enabled Windows Subsystem for Linux, installed wsl_update_x64.msi, installed Ubuntu 20.04, and ran this:
sudo apt update
And it downloads files from archive.ubuntu.com and security.ubuntu.com with astonishingly slow speed: several (below 10)KB/s, my connection is 100mbps PPPoE(translates to 11.920928955078125MiB/s download speed), undoubtly it isn't being proxied, so how can I proxy its traffic?
