I'm also interested in this one.... I'd be more than happy if I can get clearer picture of differences. Currently it seem at least three options (I'll put my comments out of my newbie knowledge - hopefully more experienced will correct me) :
- ssh tunneling : pros: easy to setup, only one port open cons: weird access to files only through core, hard to get to local machines (samba shares,printing)
- IPsec (AFAIK true secure solution, but takes more computing resources - am I wrong?
- OpenVPN - this one attracts me most, but don't know much about it. It seems like you connect virtually to LAN from remote localtion, so all accesses are much easier to handle...
I'd be glad of some further discussion on this matter... I guess we're all about secure connection from external locations... This is one of the major feature being announced on HP SmartMedia demo movies :http://www.youtube.com/user/hpmediasmart
I guess with some setup steps, we can be quite close to similar functionality under LMCE too....
Thanks in advance,
