The utility `ProxyPing` is a simple tool to ping servers behind a firewall that will not let ICMP packages through. It provides a HTTP server answering to ping requests and returning the ping delay as a HTTP text result. The tool will have to be deployed on a server behind the firewall that can be reached by a configurable TCP connection (defaulting to port TCP 6666).

A java wrapper for popular "libpcap" and "WinPcap" libraries. Accurate full API translation. Packet buffers delivered with no copies. Send custom packets, gather statistics. Comprehensive and easily extensible DPI engine.

Just test if same UDP/TCP ports are open, usefull to test firewalls/portforwards

Knocker is a simple, versatile, and easy-to-use TCP security port scanner written in C, using threads. It is able to analyze hosts and the network services which are running on them. It is available for Linux, FreeBSD, Unix, and Windows95/98/2000.

VTun is the easiest way to create Virtual Tunnels over TCP/IP networks with traffic shaping, compression, and encryption. It supports IP, Ethernet, PPP and other tunnel types. VTun is easily and highly configurable. VPN, Mobile IP, Shaping, etc

tgcd is a simple Unix network utility to extend the accessibility of TCP/IP based network services beyond firewalls. This can also be used by network analysts and security experts for penetration testing and analyze the security of their network. It's written in C Language.

Jateway is a general purpose TCP/IP connection proxy. Jateway accepts connections on arbitrary ports (like 80 or 443) and specific host:port combinations (like WANIP1:443 and WANIP2:443) for multi-interface systems Supports single TCP connections (like MySQL), and multi-TCP connections like HTTP and HTTPS, and fowards them to arbitrary host/port combinations.

Easily turn a Ubuntu-based computer into a full linux router, complete with dhcpd, named/bind, iptables firewall, and packet inspection of the network traffic being routed. Deep packet inspection for layer 2 (mac), layer 3 (ipv4, ipv6), layer 4 (icmp, tcp, udp), and layer 7 (application-specific). Summary of network flows and all layers of inspected traffic is stored in a database at 1-second intervals. This database is then mined to drive the Apache/PHP web interface.

Campagnol is a decentralized VPN over UDP tunneling. It uses UDP hole punching to open connections through NAT/firewall and OpenSSL's DTLSv1 implementation for mutual authentication and encryption.

Honeybrid is a network application built to 1) administrate network of honeypots, and 2) transparently redirect live network sessions (TCP or UDP) from one primary destination host to a secondary destination host.

New improved iptables tool, based on my earlier project Easy Linux Firewall, but rewritten from scratch using Perl. It's a simple rewrite for now, but i am working on adding some new features like. Some of the improvements will be web administration panel, automatic filtering daemon, TCP listener providing easy to use API so you can integrate it on many servers and centralize them in to one Web interface to control all of them. I am open to new ideas and also any kind of contributors, because...

A simple NAT(network address translator) for IPv6 (Linux only). Make sure if you really need it before using it. Functions: 1. IPv6 auto configuration; 2. TCP, UDP and ICMP-Echo port forwarding; 3. static port mapping for TCP and UDP.

These three tools build Checkpoint, Cisco ASA or Netscreen policys from logfiles. They write dbedit, access-list or set address, set service and set policy commands for the traffic seen in the logs, that can be cut and pasted into the firewalls. WOOT

BrFW is an application firewall, the user will specify what programs are able to open sockets (RAW / IP / UDP / TCP...). BrFW alerts when another program try to access the network.

PHANTUM - Punch-Hole Access for NAT Traversal of UDP in a Module; Built on top of Samy Kamkar's 'chownat' script, PHANTUM allows for pure client-agnostic TCP services to be tunneled over UDP and hosted behind NAT infrastructures.

A very simple to use java firewall testing tool. Ever wanted to verify that a TCP or UDP network path is actually open? This tool has both server and client modes so you can test network paths between any two computers that have the Jave JRE installed.

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.

user-space single-port unidirectional tcp proxy which handles out-of-band data, and telnet-through firewall tunnelling.

A lightweight, compact, stand-alone, platform-independent application to forward TCP (over IPv4 or IPv6) connections to another host. Possible uses include - but not limited to - firewall hacking, tunneling, proxying, fortifying ADSL, creating multi-plat

Portfwd is an user-level tool which forwards incoming TCP connections and/or UDP packets to remote hosts.

Authdefender is a filtering application that, in combination with iptables, blocks malicious users from accessing any aspect of the server in question. Malicious users are defined by brute force ssh/ftp attempts and blocked regardless of tcp wrappers.

fudp simple udp flooding utility with some nice features.
