From the iVPN web site: "iVPN is an application that makes use of the standards based PPTP and L2TP IPSec VPN server installed with Mac OS X. This VPN server is usually only available on Mac OS X Server and configured through the Server Admin application. iVPN makes it possible to use the same server utility on the client version of Mac OS X. All you have to do to set it up is to enter the user name and password that you want your VPN clients to use, the IP address range you want to give to your clients and then click start server. iVPN will handle all the other settings and start the VPN server."
Version 4.8 adds/changes the following:
Do not use iVPN on Mac OS X Server; you will no longer be able to use Mac OS X's Server Admin to configure your VPN server if you do.

Of course, Mac OS X Server includes many more, in addition to offering more recent versions of many of the above servers.

These are applications that are newer and of potential interest, but which I haven't yet selected for permanent inclusion. Have a look, and let me know if you think they deserve to be part of the permanent collection!
