IPFW losing rules after reboot

Question

I am trying to block port 137 UDP and TCP and after I reboot the rules are gone. I run the following commands:
sudo ipfw add 1 deny tcp from any to any 137 out
sudo ipfw add 2 deny udp from any to any 137 out
Before a reboot I run sudo ipfw list and things look great.....reboot and run it again and I just see the default rule.
Probably a stupid question, but I can't find the answer anywhere and I am a noob with ipfw. And Leopard just mixes the whole process up as well with ipfw and its new application firewall.
So I guess my questions are: Why do the rules disappear? How do I get the rules to stay?
Thanks,
Dan

Hi
It sounds like you need to configure a startup script without a startup script when you reboot your computer- the computer "forgets" the ipfw rules
You can google the search terms : "ipfw startup script " "launch daemons ipfw " " ipfw rules gone after reboot" "shell script launch firewall rules ipfw" "ipfw startup plist " -OR-
You can use WATERROOF waterroof is a free application that will help you configure your ipfw rules waterroof will also install a startup script and a startup plist on your hard drive
