None of the choices.
Explanation:
ipchains is a free software based firewall running on earlier Linux. It is a rewrite of ipfwadm but is
superseded by iptables in Linux 2.4 and above.
Iptables controls the packet filtering and NAT components within the Linux kernel. It is based on
Netfilter, a framework which provides a set of hooks within the Linux kernel for intercepting and
manipulating network packets.
