After upgrading from 14.3-RELEASE-p9 GENERIC to 14.4-RELEASE-p3 GENERIC I h= ave got broken kernel nat. I have the FreeBSD host box with a lot of jails. The packet path is that: cetus (jail) <-> bridge (local net) <-> lupus (jail) <-> bridge (hoster net) <-> uplink <-> internet <-> badger I run on the cetus: echo 1 | nc -N -u -p 55555 badger 5201 and on the badger i see: IP (tos 0x0, ttl 59, id 43400, offset 0, flags [none], proto UDP (17), leng= th 30) *.9.0.244.55555 > *.230.26.243.5201: [bad udp cksum 0x893c -> 0x44a5!] = UDP, length 2 I try 14.3-RELEASE-p9 GENERIC and get the same. But with 14.3-RELEASE-p9 GENERIC i get IP (tos 0x0, ttl 59, id 49222, offset 0, flags [none], proto UDP (17), leng= th 30) *.9.0.244.55555 > *.230.26.243.5201: [udp sum ok] UDP, length 2 --=20 You are receiving this mail because: You are the assignee for the bug.=
