If you are not hip to pfSense I suggest you check it out. It is an open source firewall that is making waves in InfoSec. The pfSense guys have a great howto for configuring IPSec VPN on the pfSense firewall as well as making connections via a freeware Windows IPSec VPN client called Shrew Soft which can be read by clicking here. The only item lacking in the article is a recommendation for a Mac OSX client as well as configuration tips for a Mac OSX client which is the sole point of this article. Below is information about where to download a freeware Mac OSX IPSec VPN client and then the necessary configuration to make a connection to the suggested settings noted in the howto of the pfSense web site.
I decided to finally make the jump to some sort of information manager after a talk I had with someone at work today. When working for so many companies , managing so many devices, and being a member of so many web communities it is almost impossible to remember login information, IP information, and random other notes about every installation, web site, etc. I started looking for a solution where I could at least store devices, I could access this information from anywhere (at least on my Touch), and it was secure. I was pleasantly surprised by SplashID which will allow you to store all sorts of information in all sorts of ways. The best part is that when it boils down to it this information is going to be more secure in a solution like SplashID, which uses encryption that tops banks, versus being spread through out various notepads, documents, emails, and other places on numerous computers and possibly even on paper.
