The issue seems to be that the client is behind NAT but you forgot
to add a parameter virtual_private to config setup. That's what the
"no connection is known for" error says. Add something like this
to your config setup section:

Huh? If you leave this parameter out, Openswan will use the interface
that has the default gateway, which is probably what you want.

I would suggest to leave these two parameters out. Openswan has good defaults.

If you leave this parameter out too, it will default to the IP address
of the default gateway.

I would also suggest rightca=%same

Change your password :-)
