DNS lookups in WSL

/etc/resolv.conf

in a cmd window (WSL2?)

wsl --shutdown

Create or append to file /etc/wsl.conf

[network]

generateResolvConf = false

microsoft/WSL#1350 DNS server coming from vpn network is not reflected in WSL

By default, bash.exe will auto-generate /etc/resolv.conf every time you launch bash.exe. Then it will try to keep it up to date with changes from Windows, when bash is running.

in /etc/resolv.conf
# This file was automatically generated by WSL. To stop automatic generation of this file, remove this line.

ordering of the dns servers is incorrect when the vpn is connected

In PowerShell

Get-DnsClientServerAddress -AddressFamily ipv4 | Select-Object -ExpandProperty ServerAddresses
