Firewall Tester

The Firewall Tester is a tool designed for testing firewalls' filtering policies. It includes an Intrusion Detection System testing feature, along with a packet generator tool and a sniffer. Unlike common firewall testing tools or packet generators, ftester is capable of generating network traffic that will look like real connections to the firewall or IDS system tested, which allows users to test stateful inspection firewalls (like netfilter or ipfilter) and IDS (like snort).
