Was using a pretty decent firewall (Sofaware 500P) but noticed the more rules I added and inspected the more delay it caused on my connection. I use 50mpbs FIOS and wanted to ensure no delay and maximum bandwidth with top notch security. Astaro Firewall is my new firewall and was FREE!!!. For Home users you can use this firewall for up to 10 IP devices. This firewall has all features you would ever need. The ISO image will install the Astaro OS/Firewall on a PC and make it a dedicated firewall. Performance is super and it has so many options. http://www.astaro.com/ * Network Security â Defends your network against a wide variety of Internet threats, including denial of service attacks, port scans, worms, trojans, botnets and application exploits.
