Can anyone help with this ?

Fernando,

Have you validated the VPN config using another VPN client other than Linux ? Maybe this can help you isolate the problem.

Either way, I have tested a config here using Ubuntu 14.04.3 and vpnc (the default used by Network Manager GUI) successfully, however I have found several articles mentioning vpnc problems (there's no official patch for it, but in the links below there's the procedure to download a patched package or you can patch it yourself).

Here's my config:

config vpn ipsec phase1-interface
 edit "devstack"
 set type dynamic
 set interface "port2"
 set mode aggressive
 set peertype one
 set mode-cfg enable
 set proposal aes256-sha1
 set dhgrp 2
 set xauthtype auto
 set authusrgrp "linux"
 set peerid "UBUNTU"
 set ipv4-start-ip 10.200.250.0
 set ipv4-end-ip 10.200.250.255
 set dns-mode auto
 set ipv4-split-include "devstack_split"
 set psksecret Admin123
 next
end

config vpn ipsec phase2-interface
 edit "devstack"
 set phase1name "devstack"
 set proposal aes256-sha1
 set pfs disable
 set keepalive enable
 next
end

and here my vpnc config file:

IPSec gateway 100.x.y.z
IPSec ID UBUNTU
IPSec secret Admin123
IKE Authmode psk
Xauth username linuxusr
Xauth password Admin123

Sometimes I've got the client-side error: "vpnc: vpnc.c:1194: lifetime_ike_process: Assertion `a->next->type == IKE_ATTRIB_LIFE_DURATION' failed.", but if I just keep trying it will connect just fine even wirhout the above mentioned patch.

http://rolandtapken.de/blog/2015-06/how-connect-fortigate-ipsec-vpn-using-linux

Just keep in mind that if you connect successfully to your VPN using another client (like FortiClient or IOS VPN Client) than most likely you'll have better luck changing your VPN client software.
