Tutorial: Firewalling using netfilter/iptables in Linux 2.4
One of the major advantages of the new Linux 2.4.x kernel series is the
new packet filtering / NAT / packet mangling sybsystem, called iptables.
Iptables is the successor of ipchains and ipfwadm in 2.2 and 2.0 kernels.
Major new features are stateful firewalling, extensibility and better NAT
(Network Address Translation) support.
Topics:
- concepts behind new netfilter/iptables infrastructure
- usage of iptables
- case example of a real-world firewall
- current (experimental) netfilter work - or "what is patch-o-matic"
- writing netfilter/iptables extension modules
The tutorial will be presented by two of the netfilter core team members,
Rusty Russel <rusty@rustcorp.com.au> and Harald Welte <laforge@gnumonks.org>
