So i'm setting up a SUPER paranoid 802.11 wifi setup, and i wnated to know if theres a set of iptable rules that would allow me this Situation.

First i already know how to isolate the host from other subnets, and put the wifi on a separate subnet. For example, Lan = 192.168.1.x, wireless = 192.168.2.x. There is another rule on the guide i was following to stop wireless users from communicating with useres in the 192.168.1.x (Lan) Subnet. Is there a way to restrict this with ONE exception of one Ip (Which will be my printer) on 192.168.1.x.

In Summary a set of iptables commands that isolates a host so that they can only see one or two specified ip adress, and not be able to communicate with anyone else.

Instead of applying all of these DENY rules, your default rule should be DENY that allowing only what you need. Give me a few lines of the rules that you have in place.
