What is Packet Mangling?
Packet Mangling is best described as intentional modification In front of it packet headers Information in the Internet Protocol (IP) enters the routing. This intentional change is not harmful, but it is a process commonly used by the network administrators.
When data is transmitted from one computer to another via Internet, information is sent in a data packet. Packet headers It contains information about the sender and receiver. It also contains information about the transmitted actual data, which is called payload. process. This process is used while the packet moves through Traffic router. The translation tables can be set within the NAT Edit the source IP address and target field IP address automatically. This process is also called IP camouflage or network Masking and is one of the most commonly used Packet Mangling features.
The main table used in this process is called the Mangle table. The Mangle table contains five strings: preliminary birth, input, forward, outputand after routing. The packet comes to the router and is checked against the preliminary chain of the Mangle table. Hence he is pushed Via the translation table of translation of the network address. At this point, it is determined whether the packet is for you. If it is, the packet is directed to the Mangle table and is processed by the processes of input, forward and output, which ensures that the packet arrives at its addressed target.
There are different methods for adjusting NAT settings and creating tables for MANGET PACKET. Netfilter is one such tool. This software is known for open source applications used with Linux 2.4x to 2.6x for firewalling. Netfilter itself modifies the core modules to include the functions of the power calling in the network tank. Within Netfilter, IPTABLES have been created that allow the system administrators to configure real changes in Linux 2.4x and 2.6x packet filtering sets.
Packet MAngling is the basic function of the NAT process and is used to control data packets in a private network. It is also used to manage information on the header headers for data packets sent via the Internet.
