Hello, I have received an email from the tunnelrobot stating my endpoint is not pingable. I am able to ping my endpoint from other v6 connected locations. What action do I need to take to make the tunnelrobot happy? As the graphs on my home page also list me as 100% down (even now, while I ping myself from a remote VPS). ** LOCAL END ** root@cinderella:~# ifconfig sixxs sixxs Link encap:IPv6-in-IPv4 inet6 addr: 2604:8800:100:56::2/64 Scope:Global inet6 addr: fe80::c0a8:1a3/64 Scope:Link UP POINTOPOINT RUNNING NOARP PROMISC MTU:1280 Metric:1 RX packets:949 errors:0 dropped:0 overruns:0 frame:0 TX packets:1358 errors:6 dropped:0 overruns:0 carrier:6 collisions:0 txqueuelen:0 RX bytes:176652 (172.5 KiB) TX bytes:136274 (133.0 KiB) root@cinderella:~# tcpdump -v -i sixxs -s 1500 tcpdump: WARNING: sixxs: no IPv4 address assigned tcpdump: listening on sixxs, link-type RAW (Raw IP), capture size 1500 bytes 07:54:28.158991 IP6 (hlim 55, next-header ICMPv6 (58) payload length: 64) 2001:470:21:31::adf5:498c > cl-87.chi-03.us.sixxs.net: [icmp6 sum ok] ICMP6, echo request, length 64, seq 1 07:54:28.158991 IP6 (hlim 64, next-header ICMPv6 (58) payload length: 64) cl-87.chi-03.us.sixxs.net > 2001:470:21:31::adf5:498c: [icmp6 sum ok] ICMP6, echo reply, length 64, seq 1 07:54:29.158991 IP6 (hlim 55, next-header ICMPv6 (58) payload length: 64) 2001:470:21:31::adf5:498c > cl-87.chi-03.us.sixxs.net: [icmp6 sum ok] ICMP6, echo request, length 64, seq 2 07:54:29.158991 IP6 (hlim 64, next-header ICMPv6 (58) payload length: 64) cl-87.chi-03.us.sixxs.net > 2001:470:21:31::adf5:498c: [icmp6 sum ok] ICMP6, echo reply, length 64, seq 2 07:54:30.158991 IP6 (hlim 55, next-header ICMPv6 (58) payload length: 64) 2001:470:21:31::adf5:498c > cl-87.chi-03.us.sixxs.net: [icmp6 sum ok] ICMP6, echo request, length 64, seq 3 07:54:30.158991 IP6 (hlim 64, next-header ICMPv6 (58) payload length: 64) cl-87.chi-03.us.sixxs.net > 2001:470:21:31::adf5:498c: [icmp6 sum ok] ICMP6, echo reply, length 64, seq 3 ** REMOTE VPS ** kline@hosted:~/ackfuss$ ping6 2604:8800:100:56::2 PING 2604:8800:100:56::2(2604:8800:100:56::2) 56 data bytes 64 bytes from 2604:8800:100:56::2: icmp_seq=1 ttl=56 time=77.4 ms 64 bytes from 2604:8800:100:56::2: icmp_seq=2 ttl=56 time=70.3 ms 64 bytes from 2604:8800:100:56::2: icmp_seq=3 ttl=56 time=70.8 ms ^C --- 2604:8800:100:56::2 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 70.334/72.891/77.467/3.243 ms Regards, Matt Goff
