AmpliFi is protected by a built-in firewall. AmpliFi's firewall serves as a barricade between the outside internet and your home network. Only information requested by devices within your home network is allowed in or out. UPnP and port forwarding are supported features that can be used to configure your firewall for specific devices or applications. That being said, the firewall is not directly editable, and cannot be disabled unless you place the router in Bridge Mode and lose this and all other routing capabilities. Read more about Bridge Mode.
