Background

Having a plan for Disaster Recovery during a crisis is an important and crucial operation practice, I was tasked with implementing Starlink as a last-resort gateway for internet connection if all of our WAN links were compromised. Working with Starlink was an interesting and challenging task, with the speed and bandwidth greatly depended on the satellite positioning to the antenna that was mounted on top of a roof. Starlink proved to be able to support a handful of users during an emergency scenario which is perfect for those assigned to be in the command center to respond during time of crisis.

Starlink Topology with L2 and L3 Network Devices

As you can see from the diagram below, there were several different logical traffic flow that my boss wanted to be in production. Certain segments ran through a Firewall while another bypass the Firewall and traverse out without any policy or enforcement on the traffic. The Starlink traffic flow through multiple Access and also Distribution Stack to reach the end users and promptly traverse back out through Extended L2 segment.
