Subject:   ping6 ::1 -> No route to host
Message-ID:  <20021116122410.17819bfc.drogoh@necessary-evil.org>

I've been trying to setup an IPv6 tunnel and I believe I have everything setup for the tunnel, but I keep getting no route to host when I use ping6/traceroute6. I first thought it was something wrong with ppp, but I investigated further and I'm unable to ping6 ::1. Here are the outputs from uname -a, ifconfig -a, and netstat -rn -f inet6. Please pardon the long mail. :-)
