6:20 - 7:15 Presentation - Basic Firewall Concepts Using OpenBSD Packet Filter | Gerry Lawrence

Gerry will illustrate how to setup a firewall using Packet Filter from OpenBSD. The concepts presented will be applicable to seting up firewalls utilizing other software and operating systems (although with variations in actual syntax).

Packet Filter (from here on referred to as PF) is OpenBSD's system for filtering TCP/IP traffic and doing Network Address Translation. PF is also capable of normalizing and conditioning TCP/IP traffic and providing bandwidth control and packet prioritization. PF has been a part of the GENERIC OpenBSD kernel since OpenBSD 3.0. Previous OpenBSD releases used a different firewall/NAT package which is no longer supported.
