Open Stack

Nothing seems to be able to get through br-ex... When I try and ping
something external from the instance, traffic gets through the DVR router,
which sends traffic to the SNAT namespace, to be able to forward traffic
externally, needs to populate it's next-hop arp entry, so it sends out an
arp request... That arp request makes it to the br-ex bridge, where,
according to the flows on that bridge, simply drops the arp request (see
flows below...)

ovs-ofctl dump-flows br-ex NXST_FLOW reply (xid=0x4):

I can (and have) manually added flows with higher priorities, to allow the
arp traffic out, but manual isn't the right solution...

WHY!!!!! Why are these flows here? Any help would be greatly appreciated!

If these drop flows are suppose to be there and Openstack is suppose to
insert flows with a more preferred priority, why is Openstack not doing
this?
