Short Descriptions

iptables: is used to set up, maintain, and inspect the tables of IP packet filter rules in the Linux kernel.

iptables-restore: is used to restore IP Tables from data specified on STDIN. Use I/O redirection provided by your shell to read from a file.

iptables-save: is used to dump the contents of an IP Table in easily parseable format to STDOUT. Use I/O-redirection provided by your shell to write to a file.

ip6tables: is used to set up, maintain, and inspect the tables of IPv6 packet filter rules in the Linux kernel. Several different tables may be defined. Each table contains a number of built-in chains and may also contain user-defined chains.

libip*.so: library modules are various modules (implemented as dynamic libraries) which extend the core functionality of iptables.

Boot Script

To set up the iptables firewall at boot, install the /etc/rc.d/init.d/iptables init script included in the blfs-bootscripts package.

make install-iptables
