bridge ipfw also protect set

[KHOO Guan Chen]

Hi

I want to give internet connectivity to a pc behind my Freebsd, which is 
connected to an aDSL. I know I can add another card to my set and use 
bridge+IPFW so that the behind pc is firewalled. But will this setup
also ensure that my Freebsd set is firewalled? Could now figure it out
reading the book and article.

Thanks and sorry if this is a silly question.

Regards
