Firewalls and Webmin

[SigmaX]

Heya;
I have FreeBSD 5.3 and need to set up the firewall.  I've never done 
anything with Firewall on a *NIX system without the help of Webmin, and 
I'm new to BSD in general.  Webmin gives me an error when trying to use 
the BSD Firewall module. 

I tried doing "ipfw sh" to see what was up, and I get "ipfw: 
getsockopt(IP_FW_GET): Protocol not available"

I found a post from a while back that said I need to recompile my 
kernel.  I can't imagine that that's the case for a firewall in 
general.  I need a firewall... if I can't use Webmin (read: ipfw) I'm 
gonna need a REALLY good howto :-P. Any help?

Thanx,
    SigmaX
