This article holds my notes from when I recently tested the Redhat Ansible Automation Platform. I’ve included answers to the questions I had at the start and during my effort to install the system. You need to install this on a Redhat Enterprise Linux v8.4 server, or newer. You don’t

The situation occurred after an unexpected reboot (the UPS ran out of power during a larger power outage). The

This article discusses the process to Bridge the Ethernet switch with the SFP+ ports on the Netgate 7100 firewall appliance. The process is simple enough but there is amazingly little documentation available to help you through the process. As indicated in the title, we’re going to Bridge ports on the

When we’re done, you’ll have a load balance terminating SSL (TLS) connections with multiple Docker containers running the workload. This is how it will

This article discusses the pfSense Netgate VLAN Trunk configuration. We’re using the Netgate 7100 as the firewall appliance, and a TPLink T2500G-10TS (common and fairly generic) switch to form a Trunk between. We have a computer on each side of the Trunk, each in a different subnet. See the diagram
