Hello All,
Please I need your Help
I'm struggling (Weeks ..) to get Strongswan to work with my Blackberry Z10
Without success.
Can you please help
I get every time a Delay connection error on my BB10
Is the issue linked to : "loading EAP_MSCHAPV2 method failed" ?
What is wrong in my configuration ?
Thanks
Christian

================================================================================
Goal:
My BB10 (from the Internet) to have access to my Home Network
Mobile BB10:
Blackberry Z10 Client in the Internet, that establishes a tunneled
connection to the VPN gateway (Pi) in the home network
by using the MSCHAPv2 EAP protocol via IKEv2. (Preshared Key)
NAT Gateway:
This device, serving as a NAT-router of the home network,
performs forwarding the VPN requests of my BB10
to the VPN gateway (Pi). The gateway is accessible by the
FQDN: "ckl.freeboxos.fr" from the internet.
Local IP address of the gateway is 192.168.1.254
VPN (Pi):
Acts as the other endpoint for the VPN connection to my
Home Network 192.168.1.0/24.
Uses the StrongSwan VPN library .
StrongSwan (Version):
Linux strongSwan U5.2.1/K4.4.13+
Port Forwarded on NAT Gateway
UDP 500,4500 -- Forwarded --> 192.168.1.29

===================================IPTABLES=====================================
Adjustments to IPTABLES, so that the Pi maps the traffic of the VPN network
to its physical network adapter:
$ sudo iptables -t nat -A POSTROUTING -s 10.0.0.0/16 -o eth0 -m policy
--dir out --pol ipsec -j ACCEPT
$ sudo iptables -t nat -A POSTROUTING -s 10.0.0.0/16 -o eth0 -j MASQUERADE
