How To Install And Configure Advanced Policy Firewall (APF) On CentOS 5.3 This tutorial explains how you can install and configure APF - an interface to IPTables which lets you easily configure a full featured firewall to secure servers and workstations connected to a network. This guide describes an example installation on a server with cPanel but it's only a matter of port numbers which must be open for everything to work. APF can be used on any system.

Looks ok to me. Maybe it was temporary.
Seems that the http://www.rfxn.com is down. Also, the tar extraction line should probably omit the website.
It will be really nice to see if somebody can post some nice learning resources [books, pdf's,etc] for the APF apart from the links mentioned below:
http://www.rfxn.com/projects/advanced-policy-firewall/
http://www.rfxn.com/appdocs/README.apf
Also, you can do these changes at your APF settings:
To remove "ping: sendmsg: Operation not permitted" & "Connection timed out" issues on your server, you have to do following:
Change BLK_RESNET="1" to BLK_RESNET="0"
Restart APF.
apf -r OR service apf restart
This is a great guide, and nice explanation
