To configure two Duo proxies, follow these steps:
- Install the Duo Proxy software: Install the Duo Proxy software on two separate servers. The installation instructions can be found on the Duo Security website.
- Configure the first Duo Proxy: Open the Duo configuration file on the first server and configure it with the appropriate settings, including the API hostname, integration key, and secret key provided by Duo. Also, configure the appropriate settings for your authentication sources, such as Active Directory or LDAP.
- Configure the second Duo Proxy: Open the Duo configuration file on the second server and configure it with the same settings as the first Duo Proxy.
- Configure the load balancer: Set up a load balancer to distribute traffic between the two Duo Proxy servers. Configure the load balancer to use a health check to ensure that each Duo Proxy server is healthy and able to process authentication requests.
- Test the configuration: Test the configuration by attempting to log in to a service that is protected by Duo. Verify that the load balancer distributes traffic evenly between the two Duo Proxy servers.
That’s it! You have successfully configured two Duo proxies to provide redundancy and load balancing for your authentication traffic.
