I think that's what I did. I put socket fds into a normal HASH, with
keys being localip localport remoteip remoteport for the other socket,
then in verdict I looked up the value for that socket's key, and
redirected based on that. But that's exactly when I encountered that
problem. Or are you talking about something else?
