https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259864 --- Comment #5 from Kristof Provost <kp@freebsd.org> --- I've managed to spend a little time looking at this, and I am very confused. When we see the error messages pf rejects the packet because the acknowledgement number is too far out of the window it thinks the TCP session got to. However, it looks like it stopped updating the ack window some time ago, and I have no idea why it'd do that. The packets that should have updated it passed through just fine. Is this 100% reproducible for this setup, or does it only happen occasionally? If so, how often? When did this problem start happening (I don't think we've touched any of the relevant code any time recently.)? -- You are receiving this mail because: You are the assignee for the bug.home | help
