simple & client mode are just different rulesets within rc.firewall. You can
of course specify your very own ruleset and point rc.conf at a different
file than rc.firewall.

Two things which may help.

1) There is a keyword "me" that you can use in IPFW rules that prevents you
needing to specify the server's actual IP's.
2) fwbuilder.org is a very handy tool for generating firewall config. if the
"me" keyword is too generic, you may find it easier have a gui that can hold
different objects for each IP address useful.... rather than write
repetitive firewall script lines. Also, if you're new to firewall policy
sometimes a gui can help.

If you want advice on generating a firewall policy, well... there are some
high level design rules you can follow that helps. I've posted on this topic
a number of times to the list so just search the archives.

Lastly, and not meant in any rude way, if you haven't > man ipfw ... I
personally found it very useful.

Hope that helps
