I know that this is probably pretty basic, and you've probably chaecked it,
but you haven't *said* that you'd checked it. Do you still have forwarding
enabled on the server. You know that "echo 1 > blah/blah/forward" thing.
That's the only reason I can think of immediately why the packets on the
intranet aren't getting out.
