UFW Docker
To fix the Docker and UFW security flaw without disabling iptables
UFW is a popular iptables front end on Ubuntu that makes it easy to manage firewall rules. But when Docker is installed, Docker bypasses the UFW rules and the published ports can be accessed from outside. Almost all of these solutions are similar. It requires disabling docker's iptables function first, but this also means that we give up docker's network management function. -

KUBEE ROUTER
Kube-router, a turnkey solution for Kubernetes networking
The Kube-router is a turnkey solution for Kubernetes networking with the aim to provide operational simplicity. Networking is hard as such. In a typical Kubernetes cluster, you would need to install multiple network components for various functionality. With many moving parts it makes Kubernetes networking even harder. Kube-router provides a cohesive yet lean and powerful alternative to several network components you would use. All this from a single DaemonSet/Binary. It doesn't get any... -

Nipe
An engine to make Tor network your default gateway
Nipe is a Perl-based engine whose primary aim is to make the Tor network act as the default gateway for outgoing traffic. In practice, it configures system firewall rules (iptables) and network routing so that almost all IPv4 traffic is redirected through Tor. The tool provides commands such as install, start, stop, restart, and status to manage its behavior. When “start” is issued, it sets up the necessary rules; when “stop” is used, it attempts to remove those rules. Nipe currently operates over IPv4 and does not yet support IPv6, meaning that users with IPv6 connectivity may bypass Tor routing. ... -

Tempesta FW
All-in-one solution for high performance web content delivery
...This is a drop-in-replacement for the whole web server frontend infrastructure: an HTTPS load balancer, a web accelerator, a DDoS mitigation system, and a web application firewall (WAF). Tempesta FW is the first and only hybrid of a Web accelerator and a multi-layer firewall. This unique architecture provides seamless integration with the Linux iptables or nftables. Tempesta FW services up to 1.8M HTTP requests per second on the cheapest hardware, which is x3 faster than Nginx or HAProxy. Tempesta TLS is about 40-80% faster than Nginx/OpenSSL and provides up to x4 lower latency. -

ServerArk by wahke
Linux game server UDP flood analyzer and protector
...Es überwacht eingehende UDP-Pakete über libpcap in Echtzeit und erkennt Flood-Angriffe, die Lags verursachen oder Server zum Absturz bringen können. Verdächtige Pakete werden per iptables bereits auf Kernel-Ebene blockiert, bevor sie den eigentlichen Server erreichen. So bleibt der Game-Server auch unter starken Angriffen weitgehend spielbar, da nur legitimer Traffic bis zur Anwendung durchdringt. ServerArk kann interaktiv mit detaillierter Ausgabe oder unauffällig als Daemon mit täglichen Logdateien betrieben werden. -

fwknop
Single Packet Authorization, Port Knocking
fwknop stands for the "FireWall KNock OPerator", and implements an authorization scheme called Single Packet Authorization (SPA). This method of authorization is based around a default-drop packet filter (fwknop supports iptables and firewalld on Linux, ipfw on FreeBSD and Mac OS X, and PF on OpenBSD) and libpcap. SPA is essentially next-generation port knocking (more on this below). The design decisions that guide the development of fwknop can be found in the blog post "Single Packet Authorization: The fwknop Approach". -

HiddenWall
hidden firewall, custom firewall in kernel
HiddenWall is a Linux kernel module generator for custom rules with netfilter. (block ports, Hidden mode, rootkit functions etc). The motivation: on bad situation, attacker can put your iptables/ufw to fall... but if you have HiddenWall, the attacker will not find the hidden kernel module that block external access, because have a hook to netfilter on kernel land(think like a second layer for firewall). My beginning purpose at this project is protect my personal server, now is protect the machines of my friends. When i talk "friends", i say peoples that don't know how to write low level code. ... -

An old KSH script to block SSH brute force attempts. Originally posted to seclists.org. (https://seclists.org/fulldisclosure/2005/Sep/27) The great-grandaddy of SSH tcpwrapper / iptables, supporting SSH blocking scripts. I have made a slight alteration to the script to secure it if anyone has the old original in circulation. It has clearly come to my attention that my work was never credited by other authors which is very disappointing. While my intention was to not continue to support this code actively after release, as I was donating it to the OS Community, I would have like to have been recognized by other authors in the OpenSource community, who sadly have also sought to profit from the idea. ...
