Hi Everyone.

I was using OVS 1.x with tunneling over GRE which worked perfectly out of the box, but now i have big problems getting tunneling to work.

I'm using OpenvSwitch 2.3.2 on Debian Jessie 8.2.
I want to connect 3 Hosts, but 2 Hosts does not work either.

My /etc/network/interfaces looks like:
=====

allow-vmbr0 gre0
iface gre0 inet manual
 ovs_bridge vmbr0
 ovs_type OVSTunnel
 ovs_tunnel_type gre
 ovs_tunnel_options options:remote_ip=<PUBLIC-IP-OTHERHOST>

# Loopback device:
auto lo
iface lo inet loopback

# device: eth0
auto eth0
iface eth0 inet static
 address <PUBLIC-IP-HOST>
 netmask 255.255.255.192
 gateway <GATEWAY>

auto vmbr0
iface vmbr0 inet static
 address 10.0.1.1
 netmask 255.255.255.0
 ovs_type OVSBridge
 ovs_ports gre0
 ovs_extra set bridge vmbr0 stp_enable=true
 up ovs-vsctl set Bridge ${IFACE} stp_enable=true

=====

The other Host does use 10.0.1.2 as internal IP.

I can successfully ping the internal IP, but cannot transfer any data.
Tests with iperf aborted after 1000 seconds.

I also tried VXLAN, without success!

As i'm not sure if i have to use a controller, i tried connecting floodlight as controller, but that was no help at all.

I have no idea, what i can do anymore. Does anyone can help me out?

Kind Regards,
Oliver
