Setting up firewall using IPFW

Hi,

I need help for setting up firewall IPFW with FREEBSD FreeBSD 7.2 32BIT.

I follow this guide: http://www.cyberciti.biz/faq/howto-setup-freebsd-ipfw-firewall/

And when the guide says

Another option is open default kernel config file /usr/src/sys/i386/conf and look for IPFIREWALL option:
Code: 
# grep IPFIREWALL /usr/src/sys/i386/conf
Click to expand...

My machine says:
Code: 
# grep IPFIREWALL /usr/src/sys/i386/conf
grep: /usr/src/sys/i386/conf: No such file or directory

And I can't continue...

So anyone can post me a easy guide for install firewall with IPFW????

Thanks and sorry for my English!
 
You do have to have the sources installed to be able to compile a custom kernel.

How to get them more or less depends on how you decided to update your machine.
 
What are your requirements, exactly? In most situations you can simply load the kernel module. (If you want to build a custom kernel, as mentioned, you'll need the sources.) Read: 30.6 IPFW
