Firewalling 1.0 Introduction A traditional packet filter is one of the basic protection mechanisms for a network. This type of firewall can be installed and configured in several ways, depending upon the level of protection needed. In this assignment, you will explore how to configure a firewall. As usual, you will be using Linux as your base operating system; you’ll use iptables to make it act as a firewall. Prerequisites: Read about iptables from the following links: http://www.tldp.org/HOWTO/IPCHAINS-HOWTO.html https://help.ubuntu.com/community/IptablesHowTo http://www.linuxhomenetworking.com/wiki/index.php/ Quick_HOWTO_:_Ch14_:_Linux_Firewalls_Using_iptables A firewall configuration tool can be found at: http://easyfwgen.morizot.net/ 2.1 Lab Setup This lab consists of an internal machine and firewall running iptables along with external machines running WinXP, Linux and Backtrack. See diagram below. For the purposes of this lab we won’t be using the router at 10.10.111.1 nor the “fakebook” web server.
