With a recent kernel all TCP packets sent via sis0 have a bad checksum. Other systems using other interface types (though I don't have a broad selection to test) don't seem to suffer from this problem. There was a thread in freebsd-current describing the same/similar problem, but there were few complaints (i think they were other brands of IF) and no resolution to it, so I'm bringing it up here. dave c
