simplewall is an open-source Windows application that provides a user-friendly firewall control interface powered by Windows Filtering Platform (WFP), enabling users to block or allow outgoing and incoming network connections without diving into complex OS settings or command-line tools. The app presents a clean, intuitive UI where users can define rules based on process names, IP addresses, ports, and protocols, making it possible to restrict apps from accessing the internet or control specific traffic flows with fine granularity. ...

MultiThreaded TFTP Server Open Source Freeware Windows/Unix for PXEBOOT, firmware load, support tsize, blksize, timeout Server Port Ranges, Block Number Rollover for Large Files. Runs as Service/daemon. Single Port version also available. Download

Scan for WiFi devices, block selected connections, create dozens of networks and confuse WiFi scanners! Version 3 is in development. It is stable to use, but it is very different. It is command-line based, which allows it to offer not just more features, but make them more customizable. This software allows you to easily perform a variety of actions to test 802.11 wireless networks by using an inexpensive ESP8266 WiFi SoC (System On A Chip).

...Allows real-time monitoring of network connections being made by applications, and blocking/allowing of these per app by user. Supports use of hostname lists (Energized Blu etc) to block known tracker and advertising domains for all apps. Also allows blocking of all network connections for specified apps, blocking of all connections except for specified whitelisted connections, use of pre-configured lists of connections per app to allow/block etc.

A small tool to help downloading the IP block lists from I-Blocklist for Transmission/uTorrent/Vuze/etc, or converting the list to IPSET format for a kernel level IP blocker. Similar scripts are populated already. This one is written in C.

The aoetools are programs for users of the ATA over Ethernet (AoE) network storage protocol, a simple protocol for using storage over an ethernet LAN. The vblade program (storage target) exports a block device using AoE.

...Its main features are: - it can reject viruses using Clam Antivirus (http://www.clamav.net); - it can check for spam using SpamAssassin (http://spamassassin.apache.org); - it can block emails with particular attachment extensions during the SMTP communication using Reformime (http://www.courier-mta.org/reformime.html); - it can "rate-limit" messages that an email address can send in a defined amount of time using an embedded db through SQLite (http://www.sqlite.org). Unlike other scanners for Qmail, such as Simscan or Qmail-Scanner which are inline scanners, Qexplore is an offline scanner that first write an email to a queue resident on disk, closing the qmail-smtpd communication. ...

...Flood attacks on gaming servers are typically designed to make the players on the server lag to the point where the game is not playable. It can even crash some game servers. ServerArk automatically detects when a UDP flood attack occurs and uses kernel-level iptables rules to dynamically block those packets from being processed by the game server at all. It essentially lifts the game server "above the flood" and allows the game to still be playable, even under very heavy attacks. It can be run interactively with a high level of verbosity (to watch its logic in action), or it can be run unobtrusively as a daemon with output to daily log files (typical usage).

ipclassify is a linux user space application that blocks connections from/to hosts based on lists specified in a configuration file. Currently the block lists are in the format of, and obtained from iblocklist.com. ipclassify is multi-threaded (pthre

GNIPS is a network intrusion prevention system for Linux using Snort and iptables. It alerts user of incoming attacks on their network and allows them to block any offending hosts. It's also possible to configure GNIPS to send out alert emails.

DNBD (Distributed Network Block Device) is a read-only and caching network block device.

Bruteblock allows system administrators to block various bruteforce attacks on UNIX services. The program analyzes system logs and adds attacker's IP into IPFW table effectively blocking them. Addresses are removed from the table after expiration period

brutesshd is an application written in c/php in order to prevent bruteforce attacks through ssh. Brutesshd uses iptables/pfctl tools to block this type of attacks

CRYPT extension for Netfilter/Iptables allows you to create an encrypted communication using stream and block ciphers. It also authenticates the packets.

The Enhanced Network Block Device is an industrial-strength version of the Linux kernel NBD. It makes a remote disk look like a local block device, allowing cheap and safe realtime mirrors to be built over the net.
