--- Comment #6 from Thomas Kupper <t...@kupper.org> --- After a comment on a related OPNsense forum thread, stating that this issue may be fixed with OPNsense 25.7-RC2, I tested it again. The referenced FreeBSD-src commit is: "pf: fix ICMP ECHO handling of ID conflicts", e7abf8829d8d, from Damir Bikmuhametov, Date 2025-06-26. Using the test setup from Karsten Schmidt with FreeBSD 15 SNAPSHOT 2025-07-18 as router, it's now possible to ping using the same ICMP ID on two clients at the same time. -- You are receiving this mail because: You are the assignee for the bug.
