Hi, Need some help here :) Thinking that following Gene's v6 guide would be good Sunday afternoon fun I registered a tunnel with HE. 2001:470:1f06:ad::2 is my end of the tunnel, 2001:470:1f07:ad/64 is my assigned ip space.

<br>No luck so far though.<br>My router is OpenBSD-current, here's the config:<br><br>Tunnel:<br>~$ cat /etc/hostname.gif0<br>up giftunnel <a href="http://67.86.49.123">67.86.49.123</a> <a href="http://209.51.161.14">

<br>my end of the tunnel from their web interface, again 100% packet loss.<br>If this is relevant, my ISP is Cablevision in Connecticut.<br><br>Have I missed anything?<br>Would appreciate any hints.<br>Thank you.<br>--<br>
