Software Router for Unix

Dear Users:

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).

Thanks in advance.

You don't need routing software to do what you describe. This is simply done with static routes and a kernel configured for IP forwarding.

Unfortunately, Mac OS X doesn't seem to support this feature. Do you have any suggestions (yes, I do want to stick with OS X..).

Thanks!

It is hard to believe that the Darwin kernel (OS X) cannot be configured forward IP packets.

You're quite right. I found out that all that needs to be done is to add a few lines to the /etc/rc file...
