Linux IPTables Firewall 1.4.8
Posted May 21, 2010
Site iptables.org

iptables is built on top of netfilter, the packet alteration framework for Linux 2.4.x and 2.6.x. It is a major rewrite of its predecessor ipchains, and is used to control packet filtering, Network Address Translation (masquerading, portforwarding, transparent proxying), and special effects such as packet mangling.

Changes: Support for new features in the 2.6.34 kernel, documentation updates, and bugfixes.

NuFW Authenticating Firewall 2.4.1
Posted May 12, 2010
Authored by regit | Site nufw.org

NuFW is a set of daemons that filters packets on a per-user basis. The gateway authorizes a packet depending on which remote user has sent it. On the client side, users have to run a client that sends authentication packets to the gateway. On the server side, the gateway associates user ids to packets, thus enabling the possibility to filter packets on a user basis. Furthermore, the server architecture is done to use external authentication source such as an LDAP server.

Changes: This new release fixes some bugs in the client library and brings improvements relative to TLS support.

Authfail 1.1.7
Posted May 4, 2010
Authored by Bartek Krajnik | Site bmk.bz

authfail is a tool for adding IP addresses to an ACL when entities from those addresses attempt to log into a system, but cause authentication failures in auth.log. It reads data from auth.log in real time and adds the IP into netfilter with a DROP/REJECT policy.

Changes: New rules were added to catch more denied login attempts.

Firewall Builder With GUI 4.0.0
Posted Mar 10, 2010
Site fwbuilder.org

Firewall Builder consists of a GUI and set of policy compilers for various firewall platforms. It helps users maintain a database of objects and allows policy editing using simple drag-and-drop operations. The GUI and policy compilers are completely independent, which provides for a consistent abstract model and the same GUI for different firewall platforms. It currently supports iptables, ipfilter, ipfw, OpenBSD pf, Cisco PIX and FWSM, and Cisco routers access lists.

Changes: This is a major upgrade. It comes with support for high availability firewall configurations, including heartbeat, vrrpd, keepalived, and conntrackd on Linux, CARP and pfsync on OpenBSD, and PIX failover configuration. It can generate configuration scripts to manage IP addresses, VLAN, bridge, and bonding interfaces on the firewall. Drop-in support for OpenWRT firewall script is now available, as well as experimental integration with IPCOP firewall appliances. The has supports undo and redo of unlimited depth and was generally streamlined and improved.

Changes: This first release of the new stable branch of NuFW is a bugfix release over the latest release candidate. The main change is a protocol modification which will permit you to have a new client connect on an older server in the future.

pkd-1.6.tgz
Posted Feb 4, 2010
Authored by eric

ipt_pkd is an iptables extension implementing port knock detection. 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.

Changes: This version was updated for Linux 2.6.32 and iptables 1.4.6. A new knock client was added, which is written in C# and works on both Linux and Windows and encrypts configuration data. A pre-built kernel module, an iptables library for vyatta community edition 5, and a small install script for vyatta were added.

Web-Based Firewall Logging Tool 0.94
Posted Oct 15, 2009
Authored by Bob Hockney | Site webfwlog.sourceforge.net

Webfwlog is a Web-based firewall log reporting and analysis tool. It allows users to design reports to use on logged firewall data in whatever configuration they desire. Included are sample reports as a starting point. Reports can be sorted with a single click, or "drilled-down" all the way to the packet level, and saved for later use. Supported log formats are netfilter, ipfilter, ipfw, ipchains, and Windows XP. Netfilter support includes ulogd MySQL or PostgreSQL database logs using the iptables ULOG target.

Changes: This is a maintenance release, mostly to fix numerous but harmless PHP notice-level messages.

Changes: This version adds support for libxtables, iptables 1.4.3.2, and Linux kernel 2.6.29. A port config option was added on the Python knock, so you don't have to have a bunch of UDP ports open on a firewall to pass a knock through to an internal client.

Posted Apr 6, 2009
Authored by Victor Julien | Site vuurmuur.org

Vuurmuur is a middle-end and front-end for netfilter and iptables that is aimed at system administrators who need a decent firewall, but do not have netfilter specific knowledge. It converts human-readable rules into an iptables ruleset (or optional a bash script), makes netfilter logs readable, and includes an ncurses GUI.

Changes: Traffic shaping handling was improved. Source port randomization support was added. Support for PMTU MSS clamping was added. Generating and installing of translations was fixed. There were many other small fixes.
