How do I block (iptables) traffic on a #$%@ING bridge (br0)

From: kitepilot@kitepilot.com
------------------------------------------------------
Hello World: 

This is the scenario:
MY.DSK.BOX (eth0)  (eth?) MY.BR0.BOX (eth?)  MY.TST.BOX (eth0) 

I want to use iptables to stop unwanted traffic to traverse MY.BR0.BOX.
MY.DSK.BOX and MY.TST.BOX are in the same subnet.
The IP/subnet of MY.BR0.BOX is irrelevant because MY.BR0.BOX is invisible to 
the 'functional' network.
Yes, this WORKS (it is working now), and I can not make MY.BR0.BOX visible 
to the network because of more reasons that I have time to write about. 


WHAT I WANT:
GOOD packets are allowed to traverse MY.BR0.BOX back and forth without 
further restrictions.
BAD packets to/from MY.DSK.BOX to/from MY.TST.BOX are dropped at MY.BR0.BOX 

So far I have been able to drop the traffic in only one direction, but not 
both...   :(

Thanks!
