Installation of FWBUILDER - Which packages to take?

[Roger Grosswiler]

Hi,

i am interessted in installing fwbuilder (for the first time) so in the 
extras i found the following:

1) fwbuilder-2.0.5-3.i386.rpm       23-Jan-2005 21:22  1.3M
2) fwbuilder-ipf-2.0.5-3.i386.rpm   23-Jan-2005 21:22  161K
3) fwbuilder-ipfw-2.0.5-3.i386.rpm  23-Jan-2005 21:22  114K
4) fwbuilder-ipt-2.0.5-3.i386.rpm   23-Jan-2005 21:22  223K
5) fwbuilder-pf-2.0.5-3.i386.rpm    23-Jan-2005 21:22  125K

i haven't installed it yet, but i think i need only packages 1) and 4). 
Or will i miss some functionality without installing the others? I did 
some research, and found that pf is almost used on OpenBSD, but i didn't 
see what ipf and ipfw is differing and what they are good for.

Can you help? Thaaaaaaaaaaanks :-)
