OpenSwan/StrongSwan VPN Tunnel to Fortigate E30

[JDGrobler]

Hi there. I am battling with a configuration and all the other post are outdated and no one actually posts what they did to fix the issue they had.

I have the following that needs to be setup in the image provided.

the eth0 IP address I have managed to configure to 192.168.x.x

the setup I received for the Fortigate is as follows:

Phase 1:

AES128-SHA256,AES256-SHA256,3DES-SHA256,AES128-SHA1,AES256-SHA1,3DES-SHA1

DH GROUP 14,5

Key Lifetime = 86400

XAUTH - disabled

Phase 2:

AES128-SHA256,AES256-SHA256,3DES-SHA256,AES128-SHA1,AES256-SHA1,3DES-SHA1

DH GROUP 14,5

Enabled replay detection >

Enabled PFS

Key Lifetime seconds

Seconds 43200

I have a pre shared key that I don't know where to put.

To be honest. I have no clue what to do on the ipsec.conf file on the Raspberry Pi.

Please, to bare in mind that on the Raspberry Pi I have changed the NetworkManager so that it is the same as that on Ubuntu as I need to share the internet connection from the wlan0-eth0 with internet sharing.(found this the easiest way to achieve what was required)

The reason this is done is that the device is being used as a portable device where the cellular-modem is providing the raspberry pi with internet and the providing another device internet through the ethernet port.

However this device needs a tunnel connection through to the office.

Can someone please help me in anyway.
