I'm trying to find a software based Unix Router. I only want to bridge two subnets, and I'm not trying to share an internet connection. Ultimately, I'm looking for the sourcecode so that I can compile it for Mac OS X, which is the machine that the we want the router to run on. I'd use a Mac OS X based router, but I can't find one!! (anyone having any info on that, please pass that along as well).
