Well, where to start.
Point 1: If you are connecting to the pineapple wifi and are running anything by default there is no way of setting a whitelist/blasklist so that you are not effected by whatever you are running.
Point 2: RTFM! http://wifipineapple.com/mk5/booklet.pdf You cannot connect the pineapple to your router directly by default as the pineapple runs as an ap, you need to connect it to your MBP and setup forwarding so it shares its wifi connection with the ethernet connected to the pineapple
Point 3: Why would you do that, the pineapple has 2 interfaces for a reason!!
Point 4: DERP! get your pineapple, go to the web interface, go to network tile, go to client mode, connect to your network....DONE!
