SSHGuard protects hosts from brute-force attacks against SSH and other services. It aggregates system logs and blocks repeat offenders using several firewall backends, including iptables, ipfw, and pf.

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. For Linux, FreeBSD, OpenBSD, Solaris, OSX,etc.

Xtables-addons is a package that obsoletes the old patch-o-matic repository for the Linux kernel and iptables. Instead of patching the kernel source, extensions are built as modules and thus allow extending kernels without recompilation.

Vuurmuur is a powerful firewall manager for Linux/iptables. Vuurmuur supports traffic shaping and live monitoring. It has an easy to learn configuration that allows both simple and complex configurations, and can be fully configured through the Ncurses GUI. Vuurmuur supports NAT, Port Forwarding and has IPv6 support.

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. To reference this work: A. Papagrigoriou, P. Petrakis, M.D. Grammatikakis, "A firewall module resolving rules consistency", Workshop on Intelligent Solutions in Embedded Systems (WISES), 2017, pp. 47-50. ...

Firewall Builder is a GUI firewall management application for iptables, PF, Cisco ASA/PIX/FWSM, Cisco router ACL and more. Firewall configuration data is stored in a central file that can scale to hundreds of firewalls managed from a single UI. A message from project maintainers: After working on Firewall Builder for many years it is with some sadness that Vadim and I are announcing that we have suspended all development activity for this project.

...And I think: "Maybe I can make a client to drop the ssh-scan, like DenyHost(http://denyhost.sf.net)", so I write the "sshdprotector". dynipdrop run on linux and need iptables, I use "portsentry(http://sourceforge.net/projects/sentrytools/" + "sshdprotect" + "dynipdrop" to protect my servers, and hope this software make some help to you.

ipt_ACCT is an accounting module for iptables.

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.

The purpose of the Hi-Performance Protocol Identification Engine/HiPPIE is to analyze network traffic, and determine what protocol is in use within a given session based on packets sent to the engine. Linux kernel mod with support for iptables/netfilter

iptables-TNG ( The Next Generation of iptables) An environment that can use different packet classification algorithm (eg. tuple) to support large rulesets (more than 10,000 rules) for high bandwidth networks.

...Iptraf, tcpdump, trafshow have not such ability. Gives sorted traffic load speed on each IP. Helps detect the channel overload and maybe sources of attacks. Requeres ULOG target of iptables.

Snort_inline is a modified version of Snort. It accepts packets from iptables, instead of libpcap. It uses new rule types to tell iptables if the packet should be dropped or allowed to pass based on the Snort rules.

FPGA based hardware card which implements above 4 giga bps network traffic throughput under affordable hardware cost. With linux driver and kernel patch, software based IPTables/netfilter firewall can be easily upgraded to a multi-giga high end firewall.

Gtk-IPTables is a GTK-based frontend for iptables written in C. You can create rules for all chains for Filter, NAT, and Mangle tables.

IpTables Extension and Kernel Modul ipt_PORTNETSCAN English Detection of PORTSCAN's, NETSCAN's and COMBINEDSCAN's using quotas. Deutsch: PORTSCAN, NETSCAN und COMBINEDSCAN Erkennung auf Basis von IpTables_Regeln. Für die Erkennung können verschieden

CRYPT extension for Netfilter/Iptables allows you to create an encrypted communication using stream and block ciphers. It also authenticates the packets.

brutesshd is an application written in c/php in order to prevent bruteforce attacks through ssh. Brutesshd uses iptables/pfctl tools to block this type of attacks

A very configurable GTK based frontend for Iptables. An easy way to configure your firewall in Linux.

syndetector is a software which can detect and drop packet when a synflood attack is detected ! Based on a simple detection system (by the use of iptables and libipq) and on a simple use It is realy easy to setup this software.

A python binding for the iptables tools. The binding allows direction manipulation of the iptables through an object oriented and transaction based manner. The binding removes the need to call iptable on the command line in python applications.

nf-HiPAC is a high performance packet filter for Linux. It provides the same rich feature set as iptables but uses an advanced algorithm to minimize the number of memory lookups per packet.

IpTables / OpenS/WAN based firewall management utility.

FireWise Utilities (FWU) is a suite of tools for dynamically generating firewall tables in either binary or script format for several operating systems. Features in dev: iptables, ip6tables, ipfw, pf, SHA2 bin hashing and LZO bin compression

...Sniffer (or Sequence) Allows you to set on your server this little daemon (pasmal) monitoring tcp/ip & icmp, and on the exact good sequence (the one you only know) run processes (a firewall) - such as access list update, iptables,ipchains.
