I beg your pardon, I typed too fast.  I was referring to net-misc/openconnect, 
which is an alternative client for Cisco AnyConnect SSL VPN.  The net-
misc/openswan package is hard masked because of the security bug #499870.  You 
could try net-misc/libreswan instead, a fork of openswan.  It may just work 
with the net-misc/networkmanager-openswan plugin.

My understanding is that as long as you enable the networkmanager plugin in 
the strongswan package, it will interoperate with the networkmanager front end 
- but I have not tried it.  Reading now the relevant webpage it says that it 
is *only* available for IKEv2 - so probably not good for your use case.

Since its networkmanager plugin is only useful for IKEv2 I don't think it 
would make any odds.  You can enable it anyway and initially try it from the 
command line (/etc/init.d/ipsec start) to see if it works with the Cisco VPN 
gateway.  If it does, then try it with the networkmanager front end, but I 
don't expect this to work.  If a GUI is a must for you, libreswan with the 
net-misc/networkmanager-openswan plugin may be a better bet.
