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.
slakbootIBS (Slackware Interactive Boot Scripts) is an enhanced set of replacement boot scripts for the Slackware Linux distribution. It includes a set of control and dispatch tools for configuring and booting with colorized interactive scripts. The new boot process allows the operator to select or skip start-up components in realtime. It facilitates debugging of startup problems and allows operators to maintain a common baseline to support several local configurations or multiple servers with a single set of scripts.
Frankenwall is a bash shell script intended to create a highly secure IPTables based Linux firewall/router with QOS/traffic shaping/bandwidth management. Be certain you know exactly what your network needs before using it. The primary focus of this project is security through an intimate understanding of your networking requirements. All configuration is done by editing text files.
IP-Array is a Linux iptables firewall script written in bash. It allows the creation of precise, stateful rules, while remaining easy to configure. IP-Array supports VPN, traffic shaping (creation of custom HTB and SFQ qdiscs, classes, and filters), multiple external interfaces, multiple LANs, multiple DMZs, NAT, logging, MAC address matching, packet marking, syslog logging, and various sysctl settings. It also includes some presets and autoconfig options for common needs like DNS, FTP, SMTP.
homeLANsecurity is a series of shell scripts for loading iptables firewall rules. The goal of these scripts is to provide an easy to manage framework for standard iptables rule sets. The scripts are well documented and are easily edited. It is primarily designed to operate on home or small office gateway Linux system, but the scripts can be easily adapted to protect an individual Linux server or workstation. homeLANsecurity's command set is written to support loading, clearing, saving, restoring, testing, and displaying of iptables rules. The configuration supports NAT, port forwarding of common services, TOS packet mangling, OpenVPN, Squid transparent proxy, IP address banning, adaptive banning, and connection tuning. Custom iptables rules are easily inserted without any editing of the scripts themselves.
Lokiwall is a firewall script for Linux. In addition to the standard function of easily limiting network traffic, it features dual routing (using two Internet connections simultaniously), connection fail-over, load balancing, traffic control, advanced masquerading, advanced DNAT, and advanced marking (to direct specific traffic to a certain interface). The advanced features require some kernel patches. The standard features will work on a default Linux system with iptables and iproute2.
