what info is missing? Hi I don't think there is much hope for this bz, from a [recent exchange][1] > And OVN doesn't support distributed snat. And I'm not sure if it is even possible (I could be wrong) I would like to ask a different question: is it possible to use IPv6 and not rely on any natting at all? Something like: - each routed subnet, or hypervisor, would have a prefix associated. This prefix would be used to pick up IPs for the VM running there... - the egress traffic would leave through the hypervisor running the VM, without snat, so traffic is well distributed [1]: https://mail.openvswitch.org/pipermail/ovs-discuss/2022-March/051754.html |
