          First of all, it's important that you select the IP (or IPs) that should be allowed to route video streams.
          Those will usually be the ones for your wired connections. This configuration allows Cockpit to block other
          available IPs, like those from WiFi and Hotspot connections, preventing lag and stuttering in your video
          streams.
