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

[Jeremy Wilson]

I'm running Linux Openswan U2.4.15/K2.6.18-128.el5xen (netkey) on CentOS 
5.3 and I'm getting the following error when I try to connect to the server.

Oct 21 12:45:15 gateway pluto[7573]: "L2TP-PSK"[2] x.x.x.x #1: cannot 
respond to IPsec SA request because no connection is known for 
y.y.y.y:17/1701...x.x.x.x[192.168.1.120]:17/%any===192.168.1.120/32
Oct 21 12:45:15 gateway pluto[7573]: "L2TP-PSK"[2] x.x.x.x #1: sending 
encrypted notification INVALID_ID_INFORMATION to x.x.x.x:4500

I had it working previously and one of the other admins must have 
changed the config.

I'm assuming this is an error in my ipsec.conf file somehow.  It's 
listed below.

I'm trying to connect with a Mac.
