https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214630 --- Comment #5 from tony181116@outlook.com --- Created attachment 177326 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D177326&action= =3Dedit Showing duplicate fin packets On further investigation I have noticed duplicate FIN packets being created, although due to the set up of the machine this may or may not be helpful as= the packets are manipulated by: 1) ipfw to send them to 2) a divert socket which is used to add a GTP header to the packet. 3) back into the firewall for final dispatch to gateway. Although it did occur to me if these additional fin packets are being count= ed before the UDP header is added, then it would be possible to end up with a negative number of connections in some TCP states. --=20 You are receiving this mail because: You are the assignee for the bug.=
