Tnx much for the input. I'm the new lead sys admin here. Been away from
freebsd for far too long. It's good to be back. ;>

-}that you either need to write stateful rules (so that the initial connection
-}creates a state that is then used to allow traffic in both directions) or
That's what we currently have set up.
-}you need to create two rules -- one to allow traffic out, the other to
-}allow traffic in. Stateful filtering is generally considered to be more
-}secure, but you then have concerns about properly maintaining state tables,
-}which can be a problem on very busy servers.
Oh? Why is stateful considered more secure? Anybody have links to good
reading on this? I've been through the links in the handbook. Tho' I could
have missed something, I didn't see anything on why stateful is more secure
