--- Comment #14 from Roger Pau Monn=C3=83=C2=A9 <royger@freebsd.org> ---
Hello,

I've recently committed a bunch of netfront fixes that I think should help
solve this issue. ATM, the only reliable way to do packet forwarding on a
FreeBSD DomU is to disable all the hardware offload features on both nics
(rxcsum, txcsum, tso and lro). Could someone give it a try?

I'm also working on making forwarding work _without_ having to disable all
those features, so that we can get optimal performance, however those patch=
es
have not yet been reviewed:
