** Summary changed: - Gateway router NAT non-functional for OVN 22.03 + [hwol] centralized gateway NAT non-functional
** Summary changed: - [hwol] centralized gateway NAT non-functional + [hwol] centralized gateway NAT mangles source address ** Description changed: - I currently do not have all the details, but I do know that OVN 21.12 - and 22.03 brings a regression as to how NAT is processed for CMS'es that - make use of gateway routers, such as OpenStack. + When hardware offload is enabled, CMS configures gateway routers and + centralized NAT, the source address of packets flowing through the + gateway are mangled after the connection preamble, not allowing the + connection to form. - We've tracked the regression down to a single commit [0]. + When disabling hardware offload completely the problem goes away. + + Running ovn-northd without [0] also makes the problem go away. 0: https://github.com/ovn- org/ovn/commit/4deac4509abbedd6ffaecf27eed01ddefccea40a ** Changed in: ovn (Ubuntu) Importance: Critical => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1966981 Title: [hwol] centralized gateway NAT mangles source address To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ovn/+bug/1966981/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
