IPv6-in-IPv4 (RFC4213) Tunnel (Turris 4.0.5)

[Fortytwo]

Turris 4.0.5 / Turris Omnia

Dear Forum-Users,
i have an issue initiating a IPv6-in-IPv4- Tunnel. My Provider in Germany does not support IPv6 access in Bridge-Mode (Vodafone-Router (In BridgeMode/just CableModem) → Turris Omnia) I just get an IPv4 Address.
I want to bypass that problem by creating a IPv6-in-IPv4 Tunnel described here I have created an account at Hurricane Electric and configured “WAN6” under LuCI ( Network → Interfaces)

ping ipv6.google.com
ping: cannot resolve ipv6.google.com: Unknown host

As result I have IPv6 connectivity, but no gateway connectivity …
I checked the details, I checked the details but found no errors in the settings.

Anyone have any idea what I can do? Does anyone have any experience?

Thank you very much! with best regards from Berlin
Sebastian

Hello @Fortytwo,
could you send more details, like screenshot of details of wan6 interface or output of ‘uci show network.wan6’ command?
Don’t forget to anonymize your HE account details.

@hagrid

uci show network.wan6

root@turris:~# uci show network.wan6
network.wan6=interface
network.wan6.ifname=‘@wan’
network.wan6.proto=‘6in4’
network.wan6.peeraddr=‘216.66.86.114’
network.wan6.ip6addr=‘2001:470:6c:386::2/64’
network.wan6.username=‘XXXXXXXX’
network.wan6.password=‘XXXXX’
network.wan6.ip6prefix=‘2001:470:519b::/48’
network.wan6.tunnelid=‘578XXX’

Can you ping 2001:470:6c:386::1?
Are you able to ping some IPv6 outside your prefix, for example 2a03:2880:f13d:83:face:b00c:0:25de

[Fortytwo]

Yes , both addresses are working!

[hagrid]

Hmm… so, does the HE tunnel work?

[Fortytwo]

Yes and No.

From my Mac or from Turris (SSH):

root@turris:~# ping 2001:470:6c:386::1
ping: unknown host 2001:470:6c:386::1
root@turris:~# ping 2a03:2880:f13d:83:face:b00c:0:25de
ping: unknown host 2a03:2880:f13d:83:face:b00c:0:25de
root@turris:~#

From my iPhone both addresses are pingable!
I restarted (Mac) the networkinterface and OS without any difference results.

When I check https://ipv6-test.com/ I see:

but Foris Connection test:

I am confused …

Try please

ping6 2a03:2880:f13d:83:face:b00c:0:25de

IPv6 in 4 donť have IPv6 gateway

It works then … probably
Thank you very much for your help!
