Hi, As described in this Launchpad bug https://bugs.launchpad.net/neutron/+bug/1902950, in contrast with ML2 / OVS, with ML2 / OVN there is not a masquerading forwarding DNS resolver available to instances on isolated tenant networks. The purpose of this message is to gather feedback from the community as to how much interest there is in providing this functionality under ML2 / OVN. If your organization has interest, please respond to this thread. Even better, register your interest on the topic in the etherpad for the upcoming Antelope PTG (https://etherpad.opendev.org/p/neutron-antelope-ptg) under the "Check of interest on closing ML2/OVN DNS gaps" topic. And of course, attend the conversation in October Best regards Miguel Lavalle
