It's not, in short.  You'll have to take your ipchains script and
convert it into either ipfw (the native FreeBSD firewall), or ipfilter
(the portable firewall).  It's probably easier to use ipfw, as I /think/
it's closer to the Linux stuff.

If you want to get a good idea of what you're letting yourself in for,
here's the manual page for ipfw describing the command language:


And the home page for ipfilter is at:


Anyway, ipchains is 2.2, I think in 2.4 you have to use netfilter
instead.  :-)
