I need to block all ports except smtp from the outside world to my machine that runs natd. My server's setup is two network cards, one to Internet(dc0) and one to LAN(dc1). I made the necessary adjustments to get natd working. It does, and users on LAN can access the internet w/ ipfw add all ip any to any. This is how I really want ipfw configured instead: Allow my users access to any resource/port on Internet & any resource/port on my server running natd/ipfw. Disallow every Internet user access to every port on my server running natd/ipfw except port smtp. I'm not sure which which commands to give ipfw. I tried editing the ones in rc.firewall (simple and client) but those rules seemed to stop all access to the Internet. It should be really simple. I'm probably missing some easy concept that I should have caught by reading the manpages, freebsd-questions, etc. concerning this topic.
