Problem solved.
As expected, it was evidently a network problem on the Contabo side.

Recently I'm experiencing IPv6 connectivity issues through tunnelbroker to various sites, preventing webpages from loading:

Specific example:

Through tunnelbroker: ping6 substackcdn.com
PING6(56=40+8+8 bytes) 2001:470:.... --> 2600:9000:24eb:ee00:4:b4b9:d3c0:93a1
^C
--- substackcdn.com ping6 statistics ---
5 packets transmitted, 0 packets received, 100.0% packet loss

From a cloud server with direct IPv6 service:

ping6 substackcdn.com
PING substackcdn.com(2600:9000:...) 56 data bytes
64 bytes from 2600:9000:2269:7200:4:b4b9:d3c0:93a1: icmp_seq=0 ttl=56 time=1.17 ms

See if this works:
Quote
ifconfig sit1 inet6 add 2001:470:1f1a:21e::2/64 tunnel ::216.66.87.14 up
route -6 add default dev sit1
If you have “ip” available, using it to bring up the tunnel is cleaner.

Sit0 does not need to be brought up.

Hi,
same problem here (I have a VPS in Düsseldorf Contabo datacenter).
The cause seems to belong to Contabo.
I contacted Contabo support but so far I have not received any confirmation regarding the cause (nor regarding the existence of the problem...).
In any case (and I think it's not accidental) two days ago Conbabo communicated (see "Scheduled Maintenances" here:https://contabo-status.com/) that it had scheduled (for next Monday) a network maintenance intervention.

Hello,
First sorry for my bad english.

With your Setup was my ipv6 tunnel not work.

I take anythink and only 30 seconds was the gateway up and after this 30 seconds down.

I have a Sophos XG with v19

Can you add a step by step tutorial to add a ipv6 Tunnel in Sophos XG v19

Example: at 6to4 i can only add the local ipv4 address not remote
And then come a popup where i can only add the destination IP/Prefix.
If you can post an example ipv6 infos from HE.NET and the Sophos XG v19 pictures step by step??
Please add the Rules(ipv4, ipv6 and nat) pictures too.
Thank you

Hi,

i have mailed dnsadmin about this issue and they replied to me:

Hello,

The recent DNS resolution issues should be resolved at this point.

Please test again and let us know if you still see any issues.

Hello all,

I have setup an IPv6 Tunnel with HE. When I created the tunnel I picked Tokyo as the location as that is the closest to me, however it seems that all my traffic is being routed to the USA which well, has slowed down downloads being made through ipv6.

Is this normal? I thought if I picked Japan as the server the traffic would there but not?

If I run a trace route this is what it shows:

Code: [Select]
# /usr/sbin/traceroute6 -w 2 -I  -n  -m '18'  '2001:dc2::1'
traceroute6 to 2001:dc2::1 (2001:dc2::1) from 2001:470:23:2fc::2, 18 hops max, 20 byte packets

Hi.
As of yesterday, one of our servers using IPv6 via HE cannot reach a VPS we have at Contabo. Traceroute stops somewhere around twelve99.net, two hops after as1299.gige-g2-9.core1.fra1.he.net.
We have no issues from other IPv6 nodes, while a second TB connection (my home) cannot reach the host as well!

Is there something on HE side?

Thanks
