I posted this to the user group and haven't got an answer. I was wondering if anyone in this group would have info....

I was also reading information from http://ac2i.tzo.com/bridge_filter/
 that talks about a patch that will add the chain bridgein. Is this chain
 built in with the new kernels or do I still need to use the patch? Also with
 this do I still need the brcfg utility? Hopefully someone can answer my
 questions.
