sshdfilter automatically blocks ssh brute force attacks by reading sshd log output in real time and adding iptables rules based on authentication failures. Block rules are created by logging on with an invalid user name, or wrongly guessing the password for an existing account. Block rules are removed after a week to maintain a small list of blocks. It also comes with a LogWatch filter.

Arno's IPTABLES Firewall Script is a secure stateful firewall for both single and multi-homed machines. It supports NAT and SNAT, port forwarding, ADSL ethernet modems with both static and dynamically assigned IPs, MAC address filtering, stealth port scan detection, DMZ support, protection against SYN/ICMP flooding, experimental IPv6 support, multi-interface/aliased-IP support, and extensive user definable logging with rate limiting to prevent log flooding. It has plugin support to add extra features (like SSH Brute Force protection and (Racoon) IPSEC support). It is easy to configure and highly customizable. A filter script that makes your firewall log more readable is also included.

nftables aims to replace the existing {ip,ip6,arp,eb}tables framework. It provides a new packet filtering framework, a new userspace utility, and a compatibility layer for {ip,ip6}tables. nftables is built upon the building blocks of the Netfilter infrastructure such as the existing hooks, the connection tracking system, the userspace queueing component, and the logging subsystem.

fwknop implements an authorization scheme called Single Packet Authorization that requires only a single encrypted packet to communicate various pieces of information, including desired access through an iptables, ipfw, or pf firewall policy and/or specific commands to execute on the target system. The main application of this program is to protect services such as SSH with an additional layer of security in order to make the exploitation of vulnerabilities much more difficult. The authorization server works by passively monitoring authorization packets via libpcap. Also supported is a robust port knocking implementation based around iptables log messages.

ips-qos is a flexible firewall and traffic shaping tool. It was formerly offered as installers for the popular Linux distributions. The current version is available under Debian GNU/Linux. It was intended to give administrators more control over a shared Internet connection. It includes ips, a flexible and easy-to-use configurable firewall with the ability to control access to the Internet (or selected services) from a LAN. It also includes qos, a traffic shaping tool that measures and controls the traffic load for every computer in a LAN.

ipt_pkd is an iptables extension implementing port knock detection with SPA (single packet authorization). This project provides 3 parts: the kernel module ipt_pkd, the iptables user space module libipt_pkd.so, and a user space client knock program. For the knock packet, it uses a UDP packet sent to a random port that contains a SHA-256 of a timestamp, small header, random bytes, and a shared key. ipt_pkd checks the time window of the packet and does the SHA-256 to verify the packet. The shared key is never sent.

fwsnort translates snort rules into an equivalent iptables ruleset. By making use of the iptables string match module, fwsnort can detect application layer signatures which exist in many snort rules. fwsnort adds a --hex-string option to iptables, which allows snort rules that contain hex characters to be input directly into iptables rulesets without modification. In addition, fwsnort makes use of the IPTables::Parse Perl module in order to (optionally) restrict the snort rule translation to only those rules that specify traffic that could potentially be allowed through an existing iptables policy.
