I was recently reading an article in sysadmin mag website ( which describes setting up a wireless nat system. I noticed the nat setup is different, for example the option shown in rc.conf (ipnat_enable) and the nat options for port redirection. I checked the online user's guide at freebsd.org, and it looks the same as 4.3. Have these arguments changed? I was considering upgrading from 4.3 to the latest, and just want to avoid 12 hours of banging my head off the wall. Thanks for any info.
