/etc/rc.d/init.d/iptables could be the start/stop script which 
loads /etc/rc.d/init.d/firewall/default, which has the definitions for 
internal and external IPs, etc. The bootscripts could 
install /etc/rc.d/init.d/firewall/sshd, and /etc/rc.d/init.d/sshd would have:

 if [ -x /etc/rc.d/init.d/firewall/sshd ] ; then
  loadproc /etc/rc.d/init.d/firewall/sshd start
 loadproc sshd

 killproc sshd
 if [ -x /etc/rc.d/init.d/firewall/sshd ] ; then
  loadproc /etc/rc.d/init.d/firewall/sshd stop

firewall/sshd can be -x by default, or whatever. This way a usable example is 
installed, but you don't have to use it. Any personalized rules, like 
redirecting or whatever, can be in /etc/rc.d/init.d/firewall/default.
