  1. Enable systemd in WSL (needed for proper sshd):
  # /etc/wsl.conf
  [boot]
  systemd=true
  2. Install and enable sshd:
  sudo apt install openssh-server
  sudo systemctl enable ssh
  sudo systemctl start ssh
  3. Windows firewall rule (from PowerShell admin):
  New-NetFirewallRule -Name "WSL SSH" -DisplayName "WSL SSH" -Direction Inbound -Protocol TCP -LocalPort 22 -Action Allow
  4. Port forwarding from Windows to WSL (WSL2 has its own network):
  # Get WSL IP
  wsl hostname -I

  # Forward port 22 from Windows to WSL
  netsh interface portproxy add v4tov4 listenport=22 listenaddress=0.0.0.0 connectport=22 connectaddress=<WSL_IP>
  
  echo "[wsl2]`nvmIdleTimeout=-1" > $env:USERPROFILE\.wslconfig
  wsl --shutdown
  wsl -d Ubuntu -e echo "WSL restarted"
  
  On LAMP Windows side, create C:\Scripts\wsl-startup.ps1:

  # Wait for WSL to be ready
  Start-Sleep -Seconds 5

  # Start WSL and get its IP
  $wslIp = (wsl -d "Ubuntu 24.04" hostname -I).Trim().Split()[0]

  # Update port forwarding
  netsh interface portproxy delete v4tov4 listenport=22 listenaddress=0.0.0.0 2>$null
  netsh interface portproxy add v4tov4 listenport=22 listenaddress=0.0.0.0 connectport=22 connectaddress=$wslIp

  # Start sshd and keep WSL alive
  wsl -d "Ubuntu 24.04" -e sudo /usr/sbin/sshd
  wsl -d "Ubuntu 24.04" -e sleep infinity

  Then replace the scheduled task:

  # Remove old task
  Unregister-ScheduledTask -TaskName "WSL-KeepAlive" -Confirm:$false

  # Create new one
  $action = New-ScheduledTaskAction -Execute "powershell.exe" -Argument "-ExecutionPolicy Bypass -WindowStyle Hidden -File C:\Scripts\wsl-startup.ps1"
  $trigger = New-ScheduledTaskTrigger -AtStartup
  $settings = New-ScheduledTaskSettingsSet -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries
  Register-ScheduledTask -TaskName "WSL-SSH-Ready" -Action $action -Trigger $trigger -Settings $settings -RunLevel Highest -User "SYSTEM"
