Test your firewall by Packet Crafting
Packet crafting is the technique through which an attacker finds vulnerabilities or handy points within your firewall. This is ended by manually generating packets to test network devices and behaviour, otherwise of using existing network traffic. Testing may plan the firewall, IDS, TCP/IP stack, router or any new component of the network. Packets are usually created by using a packet generator or packet analyzer which allows for specific options and flags to be set as regards the created packets.
These tools help you achieve that more easily. Below are the tools that you can use to test your firewall.

- TCP, UDP, ICMP Header maltreatment
- Testing firewall and IDS rules
- Recreating traffic traces
- Network and TCP/IP implementation psychiatry
Scapy
Interactive packet pronounce-calling tool. Scapy is a powerful interactive packet exploitation tool, packet generator, network scanner, network discovery tool, and packet sniffer. It provides classes to interactively make packets or sets of packets, misuse them, send them again the wire, sniff accessory packets from the wire, be of the same opinion answers and replies, and more. Interaction is provided by the Python interpreter, consequently Python programming structures can be used (such as variables, loops, and functions). Report modules are realistic and easily reached to make.

Nemesis
Nemesis is a command-extraction UNIX network packet injection suite.Nemesis is a unconditionally powerful suite of packet crafting tools.Nemesis is a suite of packet crafting tools for the subsequent to than protocols: arp, dns, ethernet, icmp, igmp, ip, ospf, rip, tcp, and udp.Nemesis can be used for a broad range of packet crafting goals, from IDS and firewall scrutiny, to recreating traffic, to scanning for stir hosts using a variety of vary tools. Like hping2, the knack of nemesis live thing a Unix command lineage tool, allows the addict delightful general pardon in shell scripting anything test they goal to manage
Yersinia
Yersinia is a low-level protocol fierceness tool useful for shrewdness investigation. It is talented of many diverse attacks greater than multiple protocols, such as becoming the root role in the Spanning Tree (Spanning Tree Protocol), creating virtual CDP (Cisco Discovery Protocol) neighbors, becoming the responsive router in a HSRP (Hot Standby Router Protocol) scenario, faking DHCP replies, and choice low-level attacks.
Netcat
Netcat is a drifting Unix promote which reads and writes data across network connections, using TCP or UDP protocol. It is expected to be a honorable "before now-halt" tool that can be used directly or easily driven by choice programs and scripts.
