RB/532a p2p help

I currently have a staros v2 server which in turn has an ap connected to it via nic card.
I have heard before that the MT has a very good p2p filter. What I wanted to do was put a RB/532a between the server and ap, set up as little as possible just so it routes traffice to and from the machines on both sides of it while doing some p2p filtering. A quick and dirty set up on how to do this would be very much appreciated. Its about 1 year ago since I really used MT and my head is just brain washed at the moment on how staros functions. I have forgotten all the MT tricks.
