https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207055 --- Comment #2 from Kristof Provost <kp@freebsd.org> --- I'm still unable to reproduce this. The bug report (and the linked e-mail) suggest that the ICMP6 packet too big packet is rejected because the TCP header it contains has a sequence number which doesn't match the TCP connection. That's why the patch here seems to help: it bypasses the sequence number ch= eck. Clearly that's not what we want to do though. The first step is determining if the bug is in pf (incorrectly parsing the ICMP6 packet) or in the router/destination host (generating an incorrect IM= CP6 packet). In order to debug this further I'll need the pf rules and a network capture demonstrating the problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
