i've never used OpenBSD, although i hear really good things about it. i have
used FreeBSD and i think it rocks.  skip Linux.

any of the OSes you mentioned will do what you need.  both OpenBSD and FreeBSD
have IPFILTER available, and i think FreeBSD comes with ipfw.

i use IPFILTER on a sparc5 running Solaris 8 and it does everything i need and
it does it well.  so match up IPFILTER with the OS of your choice and you 
should have no problems.

if you need more help than this quick summary email me and we'll hash it out.
we can post the results of the talk here if there is interest.
