I still don't see where this would make sense for a traditional ISP model,
where the user flow goes:

users modem-----NAS-------router-----------internet

The only place port 80 is going to be intercepted here is at the router,
which is what I am doing. Are you talking about putting the *nix box
between the NAS and the router? Perhaps making the *nix box the default
route out of your NAS?
