In January, there was a thread entitled "UDP checksum trouble in -current"
where corrupted UDP checksums were observed on the wire.  A workround was
to set:

  sysctl -w net.inet.udp.do_loopback_cksum=1

and a possible patch was posted in:

  http://mail-index.NetBSD.org/tech-net/2005/01/20/0000.html

I see the same problem as the orignal poster but with bridge + ipf (I'm
running 3.0 beta), so I think we need something like this patch applied.
