The current pf.= conf isn't configured to allow any ntp packets in unless they are in the state table, if that helps anyone test things. I will see about running some tests later. I have pflogd enabled with a much longer retention period now, so hopefully I can get some captures on this. --=20 You are receiving this mail because: You are the assignee for the bug.=
