https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=193579 Bug ID: 193579 Summary: [axge] axge driver issue with tcp checksum offload with pf nat Product: Base System Version: 10.0-STABLE Hardware: amd64 OS: Any Status: Needs Triage Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: fireball@zerouptime.ch When crossing NAT from e.g. pfsense, packets sent from the axge driver will generate bad checksums (as seen in tcpdump), which eventually results in connection aborts. Test within the the same zone (i.e. not crossing NAT) generates no checksum errors and no connections aborts.
