Hey guys this is one of my first posts and I'm looking for some help setting up a VPN for a small business. Right now I have them running of a Ubuntu server running a OpenVPN network, I am looking into setting up most possibly a IPSec VPN. I am trying to keep all the software Open Source (free) to minimize the economic footprint of it in the company. If you guys would recommend something other then IPSec could it possibly be something that would work on Blackberrys and/or iPhones.
Thank you in advance.
