I’ll be focusing on using a Mac on your home network using an Airport Extreme Router (of course any router will work but the screenshots will be for the Airport). If you have a router capable of installing the Tomato Router Firmware, you should look at Donald’s full instructions because you may not need to use a Mac at all for this, your router can do it all. See Donald’s notes for other options.
Read Donald’s instructions ===> here.

After the show Dr. Matt suggested the free TunnelBlick from http://code.google.com/p/tunnelblick. I installed both and they both work well. This tutorial will be for Viscosity, but if you try Tunnelblick you have to do one thing to make it work. In the Settings, Configuration tab, select Advanced and then uncheck the box to use TunnelBlick’s tun/tap drivers.
Let’s keep going with Viscosity as our example.
Install Viscosity

In the Connection Tab Click on the Plus Button at the Bottom

Select Import Connection From File…

Thanks for this post. I need install OpenVPN Server on my mac, but it’s very difficult find a guide that in complete. The dropbox link that you have posted is expired, can you post the Donald’s Nifty Scripts of Doom file again? thx
Paolo – I’m sorry to say that Donald Burr has disappeared from the Internet and I’ve lost all normal methods of human communication with him. I searched my own drive to see if I’d saved a copy but I’m afraid I did not. I’m sorry to let you down like this.
Perhaps there could be a way to replicate the missing scripts, or at least an explanation as to what to do here…
Hi all, a copy of “Donald’s Nifty Scripts of Doom” can be located here: https://www.dropbox.com/s/1em9kwbnmzp74uh/openvpn-mac.tar.bz2?dl=0
PS. This is thanks to the wayback machine at archive.org, you should consider donating: https://archive.org

I just found Donald Burr again recently and he gave me a good link to the “Scripts of Doom”. Turns out they were in his Dropbox all along, but Dropbox changed the way you link to folders so it broke the connection. Enjoy!
Hello,
Just have a quick question, do you know how to install the OpenVPN Access Server UI?
Also, how many concurrent connections can you have with this?
Thank you!
guys this stuff no longer works…just FYI .. I got to the end to find out sysctl, ipfw and natd no longer work as expected/exist on Catalina
