First, let me recommend "sshuttle" as a VPN software - very simple, very nice way of making a quick and simple VPN with any remote server that is running OpenSSH. Only requirement is that the remote server has to have python on it. https://github.com/apenwarr/sshuttle I have used this on several OSX systems with good success. It does not work on Mavericks. The issue is explained well in this apple forum posting: https://discussions.apple.com/thread/6534813 I wonder if anyone here is using sshuttle on Mavericks and can comment ? Why is ipfw broken and poorly maintained in OSX nowadays ?
