BL1 was designed to be used as a firewall.  Few people
used that capability, so it was removed in BL2.  As far
as things being in different places, BL3 uses one startup
file (/etc/rc) while most systems have a bunch of startup
files in a separate directory ( /etc/rc.d/  or similar).
Just stick your firewall commands in /etc/rc.

Another difference between BL1 and BL3 is:  the 2.0 kernel 
(BL1) uses ipfwadm and the 2.2 kernel (BL2,BL3) uses ipchains.
So the config commands are different.

The ipchains-HOWTO has a table of differences so you should 
be able to translate your working config from BL1.

Anybody who can successfully run a firewall on BL1 is
definitely not a fool.
