The man page for ipsec.conf states, in regards to crypto 'suites':

"Perfect Forward Security (PFS) is enabled unless group none is specified."

So is PFS required if a group is specified or is it optional for the remote 
party? And is there a way to determine if PFS is being used by an existing 
connection?

I'm especially interested in OpenBSD <-> Cisco tunnels.
