How to open WinRM ports in the Windows firewall

You might already knew that, Ansible can manage Windows servers as well. And this is a supporting article for Configure Your Windows Host to be Managed by Ansible.

Ansible is using WinRM (Windows Remote Management) to connect to the Windows machines. You need to configure listener and the service on the Windows machine as part of WinRM setup and this is clearly explained in this document.

Ensure WinRM Ports are Open

Next, we need to make sure, ports 5985 and 5986 (HTTPS) are open in firewall (both OS as well as network side).

Open Windows Firewall from Start -> Run -> Type wf.msc.

(Or Open Computer Configuration -> Policies -> Windows Settings -> Security Settings -> Windows Firewall with Advanced Security -> Windows Firewall with Advanced Security -> Inbound Rules.)

Right-click the Inbound Rules node and choose New Rule.

Select the predefined rule “Windows Remote Management” from the dropdown option

Select Rules as needed

Select Allow the connections

Verify the same in console

Verify WinRM Configurations

Note: If you have already executed the ConfigureRemotingForAnsible.ps1 successfully, you can directly try the connection from an Ansible machine. Below step is to ensure that WinRM is working from same managed node.

Open a command prompt or powershell and execute winrm e winrm/config/listener.

C:\Users\Administrator>winrm e winrm/config/listener

    Transport = HTTP

Verify Port Connection

You can verify connectivity using any method but since I am using this for Ansible, I will check the port connection from my Ansible machine (Any linux machine)

$ nc -vz 192.168.99.103 5985 
Connection to 192.168.99.103 port 5985 [tcp/wsman] succeeded !

That’s it, now you can access your Windows machine over WinRM and Ansible will be able to execute playbook and tasks on your Windows machine.
