https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D216867 --- Comment #2 from Helge Oldach <freebsd@oldach.net> --- (In reply to Mark Felder from comment #1) Tested and works. However the reass should come *before* the check-state as fragments (except= the first) don't include protocol and port numbers and thus cannot match check-state anyway. We need to reassemble first, then check-state will do t= he right thing. (It doesn't harm to implement as proposed, but we may save a f= ew cycles if we reass first.) Furthermore, along the same line we should not only reassemble UDP but any = IP packet (including IPv6), which is also suggested by ipfw(8) manpage: Usually a simple rule like: # reassemble incoming fragments ipfw add reass all from any to any in is all you need at the beginning of your ruleset. --=20 You are receiving this mail because: You are the assignee for the bug.=
