[ovs-discuss] No TCP connections over OVS

i am trying to set up a SDN testbed with openvswitch and multiple Raspberry Pis. I use Ryu as controller. My problem is that i cant establish any TCP connections (I use iperf) over the openvswitch. UDP and Ping works fine, also i tested a different controller (Floodlight). Additionally when i run mininet "sudo mn --mac --switch ovsk --controller remote -x" on my PC everything works fine. My configuration for each device/raspberry looks like this:
% sudo ovs-vsctl show
I use eth0 as connection to the controller. Furthermore when i connect multiple devices(with configured openvswitch) together like normal HW switches only Ping works, but no UDP or TCP.
To make sure, that it is no Raspberry Pi/Raspbian related problem, i tested this setup with a normal PC and again no TCP only in Mininet.
I installed the openvswitch modules from the package repositories and also lsmod shows that the module is loaded.
I would really appreciate any help. Thank you in advance and
with kind regards,
