I tried this but unfortunately it did not work at all.
When the OS boots up a script runs the following command:

softflowd -i eth1 -v5 -n net

At port 10555 on localhost there is a capture script running and
10.10.2.x is the subnet I want softflowd to capture.
eth1 is the interface to capture (in promisc mode).

When I now execute the command "softflowctl dump-flows" there are flows
listed on the console which are not from the specified subnet. (btw I
also tried "net" with the same result).
Of course I restarted the softflod service and even the whole machine
after changing the configuration.

I am sorry to bother you with this issue.
Thank you again!
