The following figure shows the IPTABLES hierarchy.

The DA-662A series support the following sub-modules. Be sure to use the module that matches your

application.

NOTE

The DA-662A series do NOT support IPV6 and ipchains.

NOTE

IPTABLES plays the role of packet filtering or NAT. Take care when setting up the IPTABLES rules. If the rules

are not correct, remote hosts that connect via a LAN or PPP may be denied access. We recommend using the

Serial Console to set up the IPTABLES.

Since the IPTABLES command is very complex, to illustrate the IPTABLES syntax we have divided our

discussion of the various rules into three categories: Observe and erase chain rules, Define policy rules,

and Append or delete rules.
