netsniff-ng is a free Linux networking toolkit, a Swiss army knife for your daily Linux network plumbing if you will. Its gain of performance is reached by zero-copy mechanisms, so that on packet reception and transmission the kernel does not need to copy packets from kernel space to user space and vice versa. Our toolkit can be used for network development and analysis, debugging, auditing, or network reconnaissance.

Flexible web-based firewall log analyzer, supporting netfilter and ipfilter, ipfw, ipchains, cisco routers and Windows XP system logs, and mysql or postgresql database logs using the iptables ULOG or NFLOG target of netfilter others mapped to the ulogd format with a view. Fully supports IPv6 for database logs, and netfilter and ipfilter system file logs. Also supports Maxmind's GeoIP version 2 location databases.

ipt-netflow is high performance NetFlow exporting module for Linux kernel (up to 4.15). Designed for Linux router in high-throughput network. This is netfilter/iptables module adding support for -j NETFLOW target. Designed to work efficiently w/o conntrack. Supporting NetFlow protocols v5, v9, and IPFIX. Accounting for IPv4, IPv6 traffic, and NAT translation events (NEL). Additional options is SNMP-index translation rules, aggregation rules, Ethernet type, MPLS, VLAN, and MAC addresses exporting.

ipset_list is a wrapper script for listing sets of the netfilter ipset program. It allows you to match and display sets, headers, and elements in various ways. The result can be saved as shell script and in ipset save, or xml format.

Please see http://firehol.org/ for up-to-date releases and information. FireHOL is a stateful iptables packet filtering firewall configurator. It is abstracted, extensible, easy and powerful. It can handle any kind of firewall, but most importantly, it gives you the means to configure it, the same way you think of it.

upnpry is an upnp port opener for linux. It intercepts upnp port opening requests to routers and opens the corresponding ports on the linux box.

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. Preliminary analysis from our implementation on ARM-based embedded systems examines efficiency and scalability of our framework. ...

IPv6 to IPv6 Address Mapping Linux Kernel Module: a netfilter extension that implements IPv6-to-IPv6 address mapping (stateless NAT66 as discussed by IETF). Maps a private IPv6 address range (ULA) to a public IPv6 address range e.g. on an IPv6 router

...The reason behind this is because a lot of site administrators don't need tight security - their site is just a café which offers free internet access on an unsecured WLAN access point connected to the internet and they need a ticketing system to make it cumbersome for average people to use this offering without actually buying a single coffee. Jkaptive itself just presents the login page,checks the token and places netfilter rules. Telling apart ticketed from unticketed traffic is done through Linux' netfilter. As no proxy server is involved, jkaptive has no performance penalty, nor does it create problems with non-http traffic. Once the token is accepted, jkaptive is out of the way of any network packets completely. For presenting the login page, jkaptive has a built-in webserver, so no additional webserver application is needed.

nf_quota is an ip-based traffic accounting project. IPs can be added to users. It provides a kernel module that hooks onto netfilter and counts every packet passing a specified interface. If the quota for a ip/user is exceeded, the packet is dropped.

IP Tables State implements the "state top" feature from IP Filter for IP Tables. "State top" displays the states held by your stateful firewall in a "top"-like manner, in real time. IPTState also has an option to print your state table once and NOTE: Development has moved to github: http://github.com/jaymzh/iptstate

The PortKnocko project is composed of two parts: an iptables module (user space) and a netfilter module (kernel space). Both modules are used to implement the Port Knocking and SPA (Simple Packet Authentication).

This Netfilter module implements the IVI translation algorithm. IVI is a stateless way to provide a bridge between the IPv6 world and the IPv4 world. More information here: http://datatracker.ietf.org/doc/rfc6219/ You need DNS64 to get this work

mod_layer7 is an application switching and load balancing module for Apache 2.2.x . This module utilizes mod_proxy, mod_deflate and mod_cache and contains embedded Perl interpreter that enables request rewriting and other interesting features.

iplist is a list based packet handler which uses the netfilter netlink-queue library (kernel 2.6.14 or later). It filters by IP-address and is optimized for thousands of IP-address ranges.

TuxFrw is a set of scripts created to ease the way Linux IPTables rules are configured. Using TuxFrw an user can configure his own Linux / Netfilter based network firewall, simply passing some IP address numbers and other services utilization policie

A command line tool that allows you to (live) analyze netfilter (iptables) log files. It provides a nice output and has features like displaying hostnames, duplicate detection... More info (+ screenshots) can be found in the pdf inside the tarball.

Open-source/PHP front-end system for full gateway management based on Iptables/Netfilter, using only built-in features of Netfilter package.

The Kernel Intrusion Detection System-KIDS, is a Network IDS, where the main part, packets grab/string match, is running at kernelspace, with a hook of Netfilter Framework. The project is not ready for use, then incomplete pieces of code may be found.

Brings the functionality of Linux netfilter to Windows.

pam_iptrecent is a PAM module that interfaces with the Netfilter/IPtables Recent module IP lists. This allows PAM authenticated sessions to add (and remove) IP addresses to firewall rules on linux servers.
