Thanks! I'm trying to do as you suggested, but interestingly whenever I execute `ovs-ofctl dump-flows gtp_br0` I see that all the tables have `n_packets=0, n_bytes=0`. So, as far as I understand, the PacketOut is getting called but that doesn't reach the switch. Do you have any suggestions on what might be the problem?
Thanks again for your time.
