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 UC-7400-LX Plus supports 3 types of IPTABLES table: Filter tables, NAT tables, and
Mangle tables:
A. Filter Table —includes three chains:
INPUT chain
