SoftEtherTunnel conflicts with ipsec router Tunnel

[oegeeks]

We have 4 branches connected with ipsec-Tunnels via fortigates.
The 5.th branch, at the moment, has a fritzbox and the softether vpn Server installed.
I have to connect the new branch to the compony vpn temporaily without using ipsec-vpn.

I managed to connect some windows clients on the ipsec segment with the fritzbox branch. If i activate the softethervpn-tunnel, all other traffic to the other ipsec-vpn networks are cut of. At the moment just the standard softethervpn-hub and the openvpn module are activated.
I did not managed right now the cascade connection with routing. That will be the second step.

How to configure softethervpn, so that the ipsec-vpn-tunnels works at the same time on the same client?
I tried Tunnel-Splitting with no avail.


1. Branch: 192.168.1.0/24 (fortigate / ipsec)

3. Branch: 192.168.4.0/24 (fortigate / ipsec)
4. Branch: 192.168.5.0/24 (fortigate / ipsec)
5. Branch: 192.168.11.0/24 (Fritzbox/softethervpn)
