Hello, I have a problem on a machine (with Linux Debian Woody). I can't ping (or trace) the next router or 6bone from it. Trace 6bone from Woody: traceroute to 6bone.net (3ffe:b00:c18:1::10) from 3ffe:8271:2101:1::1, 30 hops max, 16 byte packets 1 ip6-localhost (::1) 2990.86 ms !H 2999.53 ms !H 2999.92 ms !
