How do I configure a Linux VPN Client to get into a network through a Fortigate firewall?

  • 772

In order to connect to my job's VPN, I have been given by the network admin:

  • a username
  • a password
  • a PSK

I run Ubuntu at home. I know Fortigate's VPN should be a vanilla IPSec, so OpenSwan should do the trick. Still, I can't get it to work.

I have tried a program called "Forticlient" for Linux that I found through Google but it doesn't have the appropriate fields for the 3 items listed above.

Thanks!

  1. I suggest you check out Openfortivpn. I had to resort to that, as our implementation of fortigate VPN doesn't have a functioning linux client. OpenfortiVPN works great for me:

    sudo openfortivpn -c /home/jarmund/vpnconfig

    my /home/jarmund/vpnconfig:

    host = vpn.example.com
port = 10443
username = [email protected]
password = sUpErSecReTPasW0Rd
trusted-cert = 65568d85191ad188e19e3d9396fd0065899fa1645aef40d3c9ba8e3040b1166b

    The trusted cert is the certificate offered by the VPN gateway, and will be displayed if you try to connect. Then you edit the config to add the certificate. Several certificates can be specifie on separate lines.

  2. I haven't got Fortigate here to test. But could you please try enter the Server, User and Password:

    click to Advanced Settings button and check on Use client certificate and browse to your file:

    I also gave up trying with Openswan 2 years ago: both of NETKEY and KLIPS.
