We implement an open source conflict resolution framework that consists of a user-space C application that automatically resolves firewall rules anomalies, and b) a generic tree (called policy tree), implemented as a Linux kernel module which maintains the resolved firewall rules and enables the necessary hooks to netfilter for matching incoming (or outgoing) network packets. Tree-based data structures offer improved efficiency compared to traditional access control lists (e.g. iptables or nftable maps), especially for large systems with a huge number of rules. ...

user-space single-port unidirectional tcp proxy which handles out-of-band data, and telnet-through firewall tunnelling.

A dynamic Firewall (using the iptables netfilter) which can alter its is rules on detection of certain attacks/events. Very easily modified and expendable, with mySQL back-end and dynamically loaded user-space filters.

Hank is a scalable, extensible, modular, threaded user-space program to handle all your packet juggling needs. It'll analyze, report, and act on network traffic in any protocol, at any OSI layer, at any nesting depth. And it'll do it damned fast.
