Any idea? I think you'll find that this kind of thing can be handled by pf without pf breaking a sweat. And you can ask 100 people what they think you'll find and get 100 different answers. What you really need to do is configure this setup for a controlled test. Only then will you have a good idea what to expect when you go into production.
