Hello,

since my eblocker is not yet working correctly after the update to version 2.5.6, there are still some questions regarding the recommended IPv6 deactivation in the router and client.

I am a Vodafone Cable customer and have the FB Cable 6591 as a rental device.

Is it possible to deactivate IPv6 here without any problems, and if so, which settings are required? The following options are available here:

 

Wenn keine IPv6-Internetverbindung hergestellt ist, kann die FRITZ!Box Geräten im Heimnetz Unique Local Addresses (ULA) zuweisen, damit diese untereinander kommunizieren können.


Unique Local Addresses

Wählen Sie aus, wie den Geräten im Heimnetz die Unique Local Addresses (ULA) zugewiesen werden sollen.



 

Weitere IPv6-Router im Heimnetz

Präferenz des Router Advertisement setzen (höhere Präferenzen werden von Klienten bevorzugt):


DNSv6-Server im Heimnetz

Wenn Sie einen anderen DNSv6-Server in Ihrem Heimnetz verwenden möchten, tragen Sie hier dessen IPv6-Adresse ein, damit die FRITZ!Box diese den Geräten im Heimnetz bekannt gibt.

 

 

DHCPv6-Server im Heimnetz

 

Geräte im Heimnetz sollen ihre Autokonfiguration (SLAAC) benutzen, um die eigene IPv6-Adresse zu ermitteln.

 

Geräte im Heimnetz sollen alle Nicht-IP-Adress-Informationen (z.B. DNS-Server) von einem anderen im Heimnetz vorhandenen DHCPv6-Server beziehen.

 

Geräte im Heimnetz können ihre IPv6-Adresse von einem anderen im Heimnetz vorhandenen DHCPv6-Server beziehen. Zusätzlich können sie andere relevate Informationen wie z.B. DNS-Server von diesem DHCPv6-Server beziehen. Geräte, die kein DHCPv6 unterstützen, können SLAAC (Stateless Address Autoconfiguration) nutzen.

 

Geräte im Heimnetz können ihre IPv6-Adresse von einem anderen im Heimnetz vorhandenen DHCPv6-Server beziehen. Zusätzlich können sie andere relevante Informationen, wie z.B. DNS-Server, von diesem DHCPv6-Server beziehen. SLAAC wird in diesem Modus nicht unterstützt.

Does anyone know how to disable IPv6 on my client (iMAC, OS X 10.15.7). I found here in System Preferences>Network>further Options>Configure IPv6 only the following, but there is no possibility to deactivate here (automatic, manual, only link local)

Thanks a lot in advance for your help.

I have a FB 6490  from UnityMedia, and I have internal disabled IPV6 no problems.

If you have IPV6 internal in your network enabled and your client youse also IPV6 like your MAC,

some traffic will bypassing eBlocker, so no filtering.

 

IPV6 in this case is a Privacy Risk... 🤩

Hello pio78,

i would like to know if it is enough to disable the IPV6 DHCP server (so clients will not get a IPV6 address) or do in have to disable the complete IPV6 support of the Fritz!Box for eBlocker?

Thi is not totally clear...

Thank you

Hi,

you have to disable IPV6 in the Fritzbox for the internal network.

The Fritzbox can not handel the IPV6 Pakets from your clients, so the clients

have to use IPV4.

@pio78

Thank you.

That was my understanding as well. So it would be sufficient to disable the IPV6 DHCP Server of the Fritz!Box, correct?

Then i found your Post , where you recommend to disable the external IPV6 function of the box.

It is a little bit confusing....

 

Thanks again for your answer.

Hello, since the IP anonymization is not yet working properly for me, I have to ask here again:

Before I activate the https support (here I assume the cause of all my network problems that have been going on for weeks) I first want to be sure that my IPV6 settings in the router and the clients are correct.

As mentioned above, I made the following selection in my Fritzbox 6591 Cable: "Disable DHCPv6-Server in the FRITZ!Box:".

Unfortunately, this does not complete the deactivation, because another selection must be made (see the bold texts in my first post).

 

Geräte im Heimnetz sollen ihre Autokonfiguration (SLAAC) benutzen, um die eigene IPv6-Adresse zu ermitteln.

 

Geräte im Heimnetz sollen alle Nicht-IP-Adress-Informationen (z.B. DNS-Server) von einem anderen im Heimnetz vorhandenen DHCPv6-Server beziehen.

 

Geräte im Heimnetz können ihre IPv6-Adresse von einem anderen im Heimnetz vorhandenen DHCPv6-Server beziehen. Zusätzlich können sie andere relevate Informationen wie z.B. DNS-Server von diesem DHCPv6-Server beziehen. Geräte, die kein DHCPv6 unterstützen, können SLAAC (Stateless Address Autoconfiguration) nutzen.

 

Geräte im Heimnetz können ihre IPv6-Adresse von einem anderen im Heimnetz vorhandenen DHCPv6-Server beziehen. Zusätzlich können sie andere relevante Informationen, wie z.B. DNS-Server, von diesem DHCPv6-Server beziehen. SLAAC wird in diesem Modus nicht unterstützt.

At the moment I have set my checkmark here: "There are no other DHCPv6 servers in the home network. (At the moment only the ipad, the imac and the eblocker and the Fritzbox are in my network.)
Devices in the home network should use their autoconfiguration (SLAAC) to determine their own IPv6 address".

Is this setting correct or must something else be selected?

I also made other selections and started the network devices again, but always IPV6 addresses in my clients (ipad, iMAC)  in the network settings of the Fritzbox were shown.

Also the Fritzbox network settings of the Raspberry Pi eblocker shows IPV6 addresses.

Any idea what else I could try not to get IPV6 addresses displayed on the clients in the Fritzbox?
