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.”
UC-7110 supports 3 types of IPTABLES table: Filter tables, NAT tables, and Mangle tables:
A. Filter Table—includes three chains:
INPUT chain
OUTPUT chain
FORWARD chain
B. 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)
