Comment 8 for bug 1883321

@Philipp Krivanec,
Hi, please take a look at bug https://bugs.launchpad.net/neutron/+bug/1884708 which is something related to the config `explicity_egress_direct` when the ovs-agent is using noop or iptables hybrid security group driver.
And if you have more time, take a try of this patch:

Thanks in advance.
