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

Firewalla is a small, app-based firewall that can monitor and control network traffic. It can operate in two modes and there is no monthly fee. It has a DNS cache inside, and it can block at IP layer, detect and filter out bad stuff. It works by connecting to a port in your router, and it can keep an ISP off your separate router. However, the throughput is limited to 100 megabits per second, and it can block download speeds to limit the amount of CPU being used. Customer opinions are somewhat divided, with some hailing Firewalla as a useful tool that is easy to set up and manage with advanced features, such as an onboard VPN server, to tunnel home while away. Others are not satisfied, finding it a waste of money as it has kicked their entire network offline, slowed down their web traffic or failed to perform its function effectively. One customer found it difficult to navigate, and another has experienced connectivity issues with one device, while others are unaffected.
