[Openswan Users] cannot respond to IPsec SA request because no connection is known for

[Bob Miller]

Hi,
In my experience, limited though it is, "no connection is known for"
means that the connection you described in your configuration isn't
found in reality.  It means you have either missed a configuration
option such as leftnexthop to fully describe the situation, or you have
a typo or an incorrect value for an existing option.
Also, as I understand it for nat to work, it must be enabled using
nat_traversal=yes option in your config, and your virtual_private line
must be configured correctly as well.
