Hi,
 
This is my first post to this forum.  I would like to thank everyone that has 
worked on this project.  I have been using strongSwan in a road warrior 
configuration to connect to Cisco routers.  I have been able to do this with 
several customers but recently when I tried to connect to a new customer I 
received a 40501 Notification message.  After doing some research on the 
Internet I found the following email indicating that this notification relates 
to Cisco load balancing:
http://sourceforge.net/mailarchive/forum.php?thread_name=alpine.lfd.2.00.0901271415230.2...@oynqr.eqh.erqung.pbz&forum_name=ipsec-tools-devel
 
Has strongSwan been tested with Cisco load balancing?  Has anyone else run into 
this problem?
 
I found a work around to the problem by connecting to the last server in the 
load balancing cluster, which does not return the 40501 notification, and the 
connection works fine.   This will due for my initial testing but without 
support for load balancing I will not be able to use strongSwan.  The output 
from the failed connection follows:

Thanks,
