Using Redsocks on Mountain Lion
Before 10.7, Mac OS X used IPFW, but it is now deprecated for ipfilter (pfctl) from OpenBSD.

The bug that causes sshuttle to have occasional kernel panics is not with sshuttle, but with IPFW on OSX 10.7 and 10.8, so redsocks will have the exact same issue.

Unfortunately, I don't know enough ipfilter to get it working with redsocks, but if I ever figure it out, I'll definitely share it.
