Getting started with Tailscale Access Control Lists

Tailscale's Access Control Lists (ACLs) offer a robust method for managing access within a Tailscale network by allowing users to configure rules that control connectivity between devices based on protocols, ports, and user groups. This guide is designed to demystify the complexity of ACLs and help users confidently write their first ACL rules, ensuring they do not inadvertently disrupt important connections. It includes instructions on creating ACL tests and managing SSH connections through group memberships and node tagging. The video tutorial was created in response to high demand from the Tailscale community, highlighting the need for more detailed resources on ACLs, as expressed across various social media platforms.
