I want to connect to a windows share that only accepts ipsec transport mode. I have a list of security policies and a shared secret. I've skimmed through the man page on ipsec.conf on the web and it seems to be the place to put these polices. If ipsec is part of the kernel (and I think it is, I'm using Ubuntu 12.04) do I need to install some other package in order to get this working? I'm guessing it's either openSWAN or strongSWAN but don't know the difference.
