Tatuya-san, I think this is almost certainly a network issue. I suspect that the MTU is really NOT 1500. It's probably a couple of bytes less due to tunneling or something similar. Unfortunately when I tried ping6 to test with various packet sizes, my FreeBSD 5.3-Stable box did a reboot. (No panic or dump.) Not very nice. Guess I need to look at this.
Sorry to have wasted people's time on this. If it turns out that I am wrong about this, I'll send another report. Thanks for your time! -- R.
