Open Source Windows Firewall Software - Page 9

The doorman guards the door of a server, manipulating firewall rules to admit only recognized parties. Allows Silent Running - a server with all ports CLOSED. Linux-BSD-OSX server & client; C source & docs + Windows client binary. GPL.

It's a IDS-receiver and written in C. Sometimes I want to drop remote IP xx seconds, and Undrop it when timeout; Sometimes my sniffer-server find a hack-action and I want to tell another server/server-group "Drop xxx.xxx.xxx.xxx IP xx seconds". So I written this program -- dynipdrop("dynipdrop" daemon and "ipdrop_local" to send a drop-msg from localhost, and "ipdrop_udp" to send a drop-msg to another server(installed the dynipdrop daemon). 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.

flex-fw is a small and fast console frontend to iptables with an easy syntax similar to pf, ipf or ipfw from BSD systems. The main goal was making a lightweight tool to manage tons of iptables rules on multiple Linux hosts with a similar configuration.

fli4l is a single-floppy Linux-based ISDN/DSL/ethernet-router. It features configuration with some simple ASCII-files and several possible connection-flavors (in/out/callback, raw IP/PPP, PPPoE).

iSafer firewall is used to protected your PC against spywares, spamwares. It is also a good example for software developers to understand the basic knowledge about firewall. NOTE: Visit http://isafer.sourceforge.net to see more...

Tool for use with IPFilter to do "port knocking" and grey-list filtering of SMTP connections.

A Java implementation of a NAT-PMP client. At the project's inception, there was not a well-known NAT-PMP client library for Java. This project intends to fill the gap.

JWall is not just a java gui for iptables. JWall is a multi firewall management client. A secure rulebase can be built with graphical objects. Rulesets can be pushed to remote firewalls (via ssh). The remote firewall just needs to be Linux with sshd

Monowall-CMI is an Opensource Central Management Interface for m0n0wall devices.

It's a non-complicated free patch that allows you to access websites which are censored by sublime(!) authorities like schools, offices, governments.

This Project will provide addons for the ipcop firewall.

myNetWatchman Perl Agent is a program that is designed to capture rejected packet information from various firewall logs and forward this attack information to central analysis servers at myNetWatchman.com.

Nodogsplash offers a simple way to provide restricted access to an internet connection. It is intended for use on wireless access points running OpenWRT (but may also work on other Linux-based devices).

PFL can either operate as a stand-alone firewall log parser or set up to run and configure ipfw. The major focus is parsing, compressing, and filtering *NIX (to include Mac OSX) firewall logs generated by IPFW for quick and easy admin review.

Pablesticky is a PHP script that provides a web interface to a growing amount of features of OpenBSD's PF.

A set of tools (proxy, analyzer, proxy database maintenance tools) in Perl. Of interest to those whose Internet access is blocked or censored. The tools provide an 'abstraction' of uncensored outside services, inside the censoring firewall/proxy.

We are building a more secure way to admin a serverfarm without have root-accounds after installation by using ssh and sudo.

readlog is a pair of scripts for reviewing iptables firewall logs via a handy web interface using a MySQL backend.

sshh allows you to make a persistent tcp connection (tunnel) over an http proxy. Once you have it set up, you can make new connections from either end. Similar in concept to httptunnel but more versatile and scalable.
