I'm kind of curius at this point if there is any solution to this problem:
I have a Fortigate 60f (v7.0.10) setup to handle my ipsec VPN connections. There are site to site and end to site tunnels configured and working. The Fortigate is directly connected to the internet with a public IPv Adress.
One of the end to site VPN's is using the old Shrew Soft VPN Client and I want to switch to FortiClient. After a few frustrating failed tries to set up the tunnel I realized all the internet connections I tried used DS-Lite. When I connected my notebook with the FortiClient (v7.0.7.0345) installed over the SIM card it immediatly worked.
