[Openswan Users] L2TP packets being dropped at server

I am trying to configure L2TP over IPsec using xl2tp and openswan. I've 
tried openswan 2.6.23, 2.6.24, and git master per a suggestion on IRC. 
When I bring up the connection both ends report that the IPsec SA 
transport mode was successfully established.

At that point if I start my L2TP connection I can see ESP packets 
leaving my client and reaching my host by using tcpdump. However the 
L2TP daemon doesn't appear to be receiving the packets so the client 
times out the connection.

I'm not sure where else to look at this point. Below are the the 
configuration files for both client/server as well as a barf with the 
connection established.

Client conf: http://www.bws42.com/zztmp/client.ipsec.conf
Client barf: http://www.bws42.com/zztmp/client.barf.txt
Server conf: http://www.bws42.com/zztmp/server.ipsec.conf
Server barf: http://www.bws42.com/zztmp/server.barf.txt
