[Openswan Users] NAT & noNAT

I'm using the l2tp-psk.conf from the examples directory and I can connect
NAT clients just fine if I have nat_traversal=yes.  However, when I try to
connect a non-NAT public IP, I get messages about "no connection is
known".  I have to change nat_traversal=no and comment out the "conn
L2TP-PSK-NAT" section, and public addresses can then connect.   The
settings for "virtual_private" seem to make no difference either way.  How
am I misunderstanding the example?  Is it not possible for openswan to
detect a NAT or noNAT from a client and react accordingly?

Thanks in advance.
