Hello all, I have looked for a solution to this for awhile, but havn't 
been able to find it (probably a glaringly obvious).  I have the 
following setup:

Internet   137.242.188.2        137.242.189.1
--------><--------------Firewall------------->LAN (137.242.189.0)
I use bridging to link the two together and IPFW for a firewall.  My 
problem is that all traffic that comes from the internet is broadcast 
to my entire subnet!  Visually I see this on all my switches as the 
entire thing lights up.  I know that bridging is supposed to do 
broadcasting like this, but is there a better solution.  I had ran 
routed at one point, but the majority of the experts I know say that I 
should have been doing bridging, so I switched.  Any help is much 
appriciated!  Please CC me any answers as I am not on tha mailing list 
any more.
