Firewalla: Cyber Security Firewall for Home & Business, Protect Network from Malware and Hacking | Smart Parental Control | Block Ads | VPN Server and Client | No Monthly Fee (Purple SE)

This is a truly great cyber security tool for consumers as super easy to use. For UK folks first buy an adapter US type A to UK. Then as typical FTTC customer with BT like SmartHub cannot be used in bridge mode so it will be your router so use the Purple in Bridge. Next, if like me you have a Mesh unit downstream of the BT Smarthub you will need to run the Mesh in Access Point (e.g., Bridge mode) or if your Mesh does not support bridge mode you will see only the Mesh as one unit on the Purple. Even in this double NAT with both BT and Mesh acting as routers the Purple SE in bridge still is worth having for sure but to get per device visibility the downstream mesh must be in bridge and to get full control of devices (eg segmentation and priority) you need any upstream device to Purple to be in bridge just acting as a modem. But even stuck in the middle of a double NAT (two routers) the Purple SE still does full visibility and control of in and out flows with blocking and alerts, ad block and vulnerability scans. You add full device visibility if any downstream router is in bridge and add full device control and segmentation (vlans) if any upstream router is in bridge.
