A update on some findings. If we either revert OVS commit [4], OR change a open vswitch kernel data path function [5] to always return 'false' (credits to Numan), the problem goes away.
This also appears to be a root of a different issue previously reported to the ovs-discuss list [6]. 4: https://github.com/openvswitch/ovs/commit/355fef6f2 5: https://elixir.bootlin.com/linux/latest/source/net/openvswitch/conntrack.c#L683 6: https://mail.openvswitch.org/pipermail/ovs-discuss/2022-March/051771.html -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1967856 Title: Hairpin traffic does not work with centralized NAT gw To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ovn/+bug/1967856/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
