From the compute node, ping a site on the internet:

# ping -c 4 openstack.org
PING openstack.org (174.143.194.225) 56(84) bytes of data.

See diagram explaining routing packet from VM to internet on page 18

It is shown for GRE tunnel between Compute and Neutron Node, but VXLAN tunnel will work same way. Forwarding packet from br-int to br-ex on Neutron Node in details
