IPTABLES

IPTABLES is an administrative tool for setting up, maintaining, and inspecting the Linux kernel’s

IP packet filter rule tables. Several different tables are defined, with each table containing built-in

chains and user-defined chains.

Each chain is a list of rules that apply to a certain type of packet. Each rule specifies what to do

with a matching packet. A rule (such as a jump to a user-defined chain in the same table) is called

a target.

The V2401/2402-LX supports three types of IPTABLES: Filter tables, NAT tables, and Mangle

tables.

Filter Table—includes three chains:

INPUT chain

OUTPUT chain

FORWARD chain

NAT Table—includes three chains:

PREROUTING chain—transfers the destination IP address (DNAT).

POSTROUTING chain—works after the routing process and before the Ethernet device

process

to transfer the source IP address (SNAT).

OUTPUT chain—produces local packets.
