Firewalls, Network Address Translation (NAT), network logging and accounting are
all provided by Linux's Netfilter system, also known by the name of the command
used to administer it, iptables. The iptables interface is the most sophisticated
ever offered on
Linux and makes Linux an extremely flexible system for any kind of network filtering
you might do. Large sets of filtering rules can be grouped in ways that makes
it easy to test them and turn them on and off.
Do you watch for all types of ICMP traffic--some of them quite dangerous? Can
you take advantage of stateful filtering to simplify the management of TCP connections?
Would you like to track how much traffic of various types you get?
This pocket reference will help you at those critical moments when someone
asks you to open or close a port in a hurry, either to enable some important
traffic or to block an attack. The book will keep the subtle syntax straight
and help you remember all the values you have to enter in order to be as secure
as possible. The book has an introductory section that describes applications,followed
by a reference/encyclopaedic section with all the matches and targets arranged
alphabetically.
