Unitiger, Based on your debug, if the ARP reply was to sent neutron gateway's MAC (IP: 10.0.3.101) did the mac address match the qrouter's interface on br-ex? Assuming you're using OVS. Can you check the qrouter's interface is on br-ex with ovs-vsctl show command?

Other things to check is ensure your eth2 is on the br-ex. Better yet, ensure its on ifcfg-eth2 as it lasts across reboots.

As mentioned by previous answer, check that external network is specified. However, I would ensure in /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini

[ovs]
. . .
bridge_mappings =physnet1:br-ex

Thanks, Kiran

Of course, restart network node after this and check ovs-vsctl show.
