Ansible Windows Jump Host for Secure WinRM Access -

An Ansible Windows Jump Host is essential in locked-down environments where direct access to Windows servers is restricted. In such cases, Ansible connects to target Windows nodes only through a trusted jump host. Therefore, this setup improves security while still enabling automation at scale.

Ansible manages Windows systems using WinRM. However, because of strict network controls, WinRM traffic often must pass through a bastion host. To solve this, you can configure Nginx on a Windows jump host to proxy WinRM traffic securely to multiple Windows target servers.

What Is WinRM and Why It Matters for Ansible Windows Jump Host

WinRM is a native Windows management protocol that allows remote communication over HTTP or HTTPS. Moreover, it is enabled by default on modern Windows Server versions. However, additional configuration is usually required for Ansible integration.

Because WinRM traffic is standard web traffic, it can be proxied easily. As a result, Nginx becomes a practical choice for routing WinRM requests through an Ansible Windows Jump Host.

Why Use an Ansible Windows Jump Host in Restricted Networks

In highly secured environments, only a single host may access internal systems. This host is commonly called a jump host or bastion host. Consequently, Ansible must communicate through this system instead of connecting directly.

Using an Ansible Windows Jump Host provides several benefits:

Reduced attack surface
Centralized access control
Easier auditing and compliance
Controlled WinRM exposure

At the same time, this pattern aligns well with modern DevSecOps and Zero Trust models.

Prerequisites for Ansible Windows Jump Host Setup

Before starting, ensure the following components are ready:

Ansible Controller with Ansible 2.9
Windows Server for Jump Host
Windows Server 2012 R2 or later as Target Node
Nginx for Windows
OpenSSL for certificate generation
pywinrm installed on Ansible Controller

Because of these dependencies, planning the environment upfront saves time later.

Installing Nginx on the Windows Jump Host

To begin, install Nginx on the Windows jump host. This service will proxy WinRM traffic to the backend Windows servers.

Steps to follow:

Download the stable Nginx build from https://nginx.org/en/download.html
Extract it to C:\Program Files\nginx
Start Nginx from PowerShell
Confirm the welcome page loads on http://localhost

Once verified, Nginx is ready for SSL and proxy configuration.

OpenSSL Configuration for Ansible Windows Jump Host

Secure communication is critical. Therefore, you must generate SSL certificates for Nginx.

Download OpenSSL binaries from
https://wiki.openssl.org/index.php/Binaries
Install Visual Studio 2017 if prompted
Install OpenSSL using the MSI package

Next, generate the certificate:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privatekey.key -out certificate.crt

During generation, provide the jump host IP as the Common Name. Afterward, create C:\SSL and move both files there.

Nginx Proxy Configuration for Ansible Windows Jump Host

Now configure Nginx to forward WinRM traffic securely.

Example configuration:

server {
    listen 8080 ssl;
    server_name 192.168.0.23;

    ssl_certificate     C:\SSL\certificate.crt;
    ssl_certificate_key C:\SSL\privatekey.key;

    location /192.168.0.48 {
        proxy_pass http://192.168.0.48:5985/wsman;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout 90;
        proxy_read_timeout 90;
    }
}

Here, the jump host listens on port 8080. Meanwhile, each target server maps to a unique path. As a result, multiple Windows nodes can share one Ansible Windows Jump Host.

Restart Nginx after saving the configuration.

Ansible Inventory Configuration Behind the Jump Host

With the proxy ready, configure the Ansible inventory.

Example entry:

192.168.0.48 ansible_host=192.168.0.23 ansible_user=demo ansible_password=2!ppy0ps ansible_port=8080 ansible_connection=winrm ansible_winrm_path=/192.168.0.48 ansible_winrm_server_cert_validation=ignore

In this setup:

ansible_host points to the jump host
ansible_winrm_path maps to the target node
WinRM traffic flows securely through Nginx

Because of this abstraction, Ansible playbooks remain clean and reusable.

WinRM Setup on Target Windows Servers

Ansible requires PowerShell 3.0 and .NET Framework 4.0 or higher. Therefore, older systems must be upgraded.

After upgrading PowerShell, configure WinRM using:

.\ConfigureRemotingForAnsible.ps1

This script enables HTTP and HTTPS listeners and configures authentication. Consequently, Ansible can communicate reliably with the Windows nodes.

Testing Ansible Windows Jump Host Connectivity

Finally, verify connectivity from the Ansible controller:

ansible all -i windows -m win_ping

If successful, the Ansible Windows Jump Host is working as expected.
