The branch stable/12 has been updated by kp: URL: https://cgit.FreeBSD.org/src/commit/?id=592b4f93632aa1e0bfd9f28ccfd4ab46ecc99bf4 commit 592b4f93632aa1e0bfd9f28ccfd4ab46ecc99bf4 Author: Kristof Provost <kp@FreeBSD.org> AuthorDate: 2022-06-04 10:38:40 +0000 Commit: Kristof Provost <kp@FreeBSD.org> CommitDate: 2022-06-18 07:29:56 +0000 pf: Improve route-to handling of pfsync'd states When a state if pfsync’d to a different host it doesn’t get all of the expected pointers, including the pointer to the struct pfi_kif / struct ifnet rt_kif pointer. (I.e. the interface to route out on). That in turn means that pf_route() ends up dropping the packet. Use the rule's struct pfi_kif pointer so we can still route out of the expected interface.
