On OS X 10.6 you do not have
iptables, so what is the full solution for this permanently redirect all request sent to port 80 to another port, like 8080?
It has to be persistent.

Use ipfw as in @bindbn's answer. That's the general idea.
put your rules into a file :
add at the very top of your file
add to /Library/LaunchDaemons/com.yourdomain.ipfw.plist :
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.yourdomain.ipfw</string> <key>Program</key> <string>/sbin/ipfw</string> <key>ProgramArguments</key> <array> <string>/sbin/ipfw</string> <string>-q</string> <string>/etc/ipfw.conf</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist>
Either reboot, or
launchctl load -w /Library/LaunchDaemons/com.yourdomain.ipfw.plist
the first time.
After that it is
launchctl load com.yourdomain.ipfw
ipfw add NUMBER fwd 127.0.0.1,8080 tcp from any to me 80
