@ib54003 has reported the ICMP issue in ipv6-test.com. Well, it is real. The solution is not in Turris. The solution is in the Internet Router. In FritzBox you have to enable IPv6 Ping (!) to disable filtering of ICMP messages. It is hidden under “Freigaben Gerät” (german) By default it does not work. Then you actually see ICMP working.
I checked back: Comparing 2 similar Turris Omnia devices made clear, how to achieve IPv6 ICMP working (German edition, I’m sorry):
How to enable ICMP in IPv6 with Fritz Box and Turris Omnia
In FritzBox do this:
-
Go to Internet / Freigaben.
-
Select a device for port -Freigaben from drop down. That device is your Turris Omnia. In drop down there has to be your Turris. Avoid entering anything manually!
-
In IPv6-Einstellungen check 2 boxes:
a) PING6 freigeben.
b) Firewall für delegierte IPv6-Präfixe dieses Gerätes öffnen.
Do not define opened ports as the naming suggests. Except you know what you do.
Make sure under
Heimnetz / Netzwerk / Netzwerkeinstellungen / IP-Adressen / IP-Adressen (wow!)
you check
- Unique Local Addresses (ULA) zuweisen, solange keine IPv6-Internetverbindung besteht (empfohlen)
- Auch IPv6-Präfixe zulassen, die andere IPv6-Router im Heimnetz bekanntgeben
- Diese FRITZ!Box stellt den Standard-Internetzugang zur Verfügung
- Hoch
- DHCPv6-Server in der FRITZ!Box für das Heimnetz aktivieren:
- DNS-Server und IPv6-Präfix (IA_PD) zuweisen
Turris Omnia has to be rebooted second (!!) after rebooting FritzBox. And then you experience: By default Turris Omnia does work with PD and with ICMP.
I do need help with this no-PD-without-restarting-second …
Proven to work fine.
This does actually work fine and has a high score in https://ipv6-test.com/
