Hi Bruno, there is know answer from the VPN gateway on the other end. Either the gateway cannot be reached over the network, the gateway is not running an listening on UDP port 500 or it supports the IKEv1 protocol only.

Hi,
I am having a hard time to get an IpSec VPN working in my machine... it
works fine in other OS, and I am sure I am doing something stupid here,
hope some guru can give me guidance!
I am running Ubuntu 12.10, and installed strongswan (4.5.2), added the
key secret in /etc/ipsec.secrets file, and setup the VPN through network
manager.
Without tempering with the strongswan.conf file, I have this output
(noted a similar output is :

My initial configuration file was:
--- /etc/strongswan.conf ---
# strongswan.conf - strongSwan configuration file
charon {
threads = 16
plugins {
sql {
loglevel = -1
}
}
}
pluto {
}
libstrongswan {
}
----------------
And here is the Network Manager configuration:
--- /etc/NetworkManager/system-connections/TestVPN ---
[connection]
id=TestVPN
uuid=07ac4ce3-c6c3-4d42-8bb6-29e56a8751db
type=vpn
autoconnect=false

virtual=no
encap=no
address=x.x.x.x
user=??????
method=eap
ipcomp=yes
password-flags=1
[ipv4]
method=auto
----------------
Besides the timeout issue, I noted the plugin loading issues in the
charon logs. Looking at what I got in the system by default:
$ ls /usr/lib/ipsec/plugins/
libstrongswan-addrblock.so libstrongswan-eap-tls.so
libstrongswan-pkcs11.so
libstrongswan-aes.so libstrongswan-eap-tnc.so

libstrongswan-xcbc.so
libstrongswan-eap-mschapv2.so libstrongswan-pem.so
libstrongswan-eap-radius.so libstrongswan-pgp.so
By adding the load into the strongswan.conf file at least clears the
warnings, but I am not sure on if these modules should be here, and
loaded...
Any help really appreciated!
Thanks,
