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).

SEConnector firewalling/routing gateway SECurity-System for Linux based on kernel 2.6 and iptables

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.

...is a free software project which brings a GUI for Port Knocking. The easy to use interface allows to check the server availability on the chosen port and quickly run the port knocking. No ICMP yet. Full Cocoa now! Cheers. Update V1.1 UDP added Update V1.2 "Unlimited" ports to knock through a manageable list. Still free, no reason to pay for something that simple :)

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.

[not maintained anymore] Jay's Iptables Firewall is a script with support for multiple (external/internal) interfaces, TCP/UDP/ICMP control, masquerading, synflood control, spoofing control, port forwarding, VPNs (vtund), ToS, denying hosts, ZorbIPTraff

Packet Auth. Sniffer (or Sequence) Allows you to set on your server this little daemon (pasmal) monitoring tcp/ip & icmp, and on the exact good sequence (the one you only know) run processes (a firewall) - such as access list update, iptables,ipchains.

fIreCMP is a networking utility. This is an LKM that permits a dinamic opening/closing of your port services by an ICMP packet.

Krome Shield is designed to fool remote fingerprinting tools (using ICMP & TCP), making them think you're running a different OS. It runs under Linux, using the netlink device and ipchains. In the future it will act like an IDS too, detecting attacks a

libpal is an easy-to-use, straightforward packet assembly library that allows programmers to forge any kind of IP, TCP, UDP, ICMP and application layer packages.
