IPT_PKD Iptables Port Knocking Detection 1.5
Posted Dec 5, 2009
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 release adds support for iptables 1.4.4 and 1.4.5 and kernels 2.6.30 and 2.6.31.

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.

Firewall Builder With GUI 3.0.7
Posted Sep 21, 2009
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 release fixes a security issue with temporary file handling in the generated iptables script that affects only Linux systems where Firewall Builder is used to generate static routing configuration. It also significantly improves the performance of batch compile operation, and fixes a few other minor problems. All users are encouraged to upgrade.

Linux IPTables Firewall 1.4.5
Posted Sep 15, 2009
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: This release includes updates for new features in kernel 2.6.31, bugfixes, and documentation updates.

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.

SlackFire is an firewall script implemented with iptables. It is completely configurable via a CLI, as all configuration is performed via configuration files. It supports all kinds of packet forwarding, including NAT, NAT with port redirection, and forwarding to machines with routable IP addresses. The configuration files are heavily commented, and messages in the log file are as informative as possible.

Authored by Costa Tsaousis | Site firehol.org

FireHOL a simple yet powerful way to configure stateful iptables firewalls. It can be used for almost any purpose, including control of any number of internal/external/virtual interfaces, control of any combination of routed traffic, setting up DMZ routers and servers, and all kinds of NAT. It provides strong protection (flooding, spoofing, etc.), transparent caches, source MAC verification, blacklists, whitelists, and more. Its goal is to be completely abstracted and powerful but also easy to use, audit, and understand.

Changes: See changelog.
