This is obviously a stupid question to the cognoscenti, but what do the
"input" and "output" firewall options on the ipfwadm command actually, or
are meant to be used for?
I have a LRP firewall set up up with machine "A" on the internal network
side. With no firewalling (i.e. accept all) I can ping it, read it's web
pages etc from the external side. I can then use ipfwadm -F to block http
(for example) from a specific external host. This works fine. If I then
reinstate forwading and use ipfwadm -I with similar parameters, I get the
same result. So what's the difference between F, I, and O? Is F simply a
combination of I and O for ease of use?
