Powershell Remote

Enable Powershell remote on Windows Core

On the remote endpoint enable

Enable-PSRemoting -Force
Set-NetFirewallRule -Name "WINRM-HTTP-In-TCP" -RemoteAddress Any

Mak sure the firewall profile is set to private or domain.

PS remote outside domain

If the local machine is not inside the same domain you need to add the romote endpoint as a trusted host. MITM still posible. On local machine add the remote endpoint in wsman

# Add one item
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "FQDN-or-IP"

# Add a next one if needed (see Get-Item)
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "FQDN-or-IP" -Concatenate

#Then restart WinRM
Restart-Service WinRM

Test the connection
