Only a complete reset helped me.

  • Save configuration
  • Box reset
  • Restore configuration

If you use the standard configuration (most home users without NAS, port forwarding, etc.) you can save the backup and just do a reset.

Thanks! That was exactly the problem.

After the reset (I had already tried deactivating and activating without success) I was able to activate it and now it also works with my openwrt router (without any changes).

As already suspected, you need the internet box to activate this and then it also works with third-party routers.

Uh, that’s relatively unfortunate if that’s the case everywhere. Especially since the migration is described as complete.

A large proportion of customers are not interested in the technology at all and are essentially left in limbo.

From the end customer’s perspective, a problem is only a problem when they perceive it as such, for example because something no longer works. And this is precisely the case that does not occur thanks to the dual stack.

Thanks for the lively discussion and questions.


@MichelB: Thank you (Swisscom) for taking the trouble to take a stand here.

👍

So is it correct that IPv6 on the RES network also has to be activated for third-party routers and that no (missing) switch has to be pressed anywhere or that a Swisscom router has to be plugged into the Anschluss first?

😟

Do you have internal statistics showing which third-party routers generate IPv6 packets? Or to put it another way: Are there third-party routers that work with IPv6 on the Swisscom network? That would be an important addition to my support request at AVM…

😉


Renewal interval of the dynamic IPv6 prefix

[…]


@MichelB: What is the reason why you don’t distribute static prefixes on the RES connections when the competition has been doing it for a long time without any problems? There are already use cases for this today: Decentralized backups to the NAS of the Eltern or from the NAS of the Eltern,… I would like to finally switch off this stupid DynDNS infrastructure.

🤷‍♂️

Prefix Length

[…] I can’t say in detail how to set up a Fritzbox so that it works with IPv6. However, I will have the experts check whether we can make recommendations.

Of course you get an extra medal for this. 🎖️ Thank you! I think that you will already find a FB model in your laboratory. If I can help with a packet capture on the WAN interface, let me know. I feel like this over there is not about bashing and I definitely understand the problems you have with the variety of routers. In this respect, I really appreciate your support here and would be happy to donate some time. Just win-win.

🙋‍♂️

Let us know if you find anything out.

As I wrote, my approach with a third-party router

1. IPv6 activated on third-party router, result: no IPv6 prefix

2. Old Swisscom Internet Box attached, updated, reset, IPv6 activated, result: IPv6 prefix

3. Third-party router attached again, result: IPv6 prefix

So you need a Swisscom router to change the flag on the Anschluss so that you get IPv6, then it also works with the third-party router

No, this is still the status quo. I got rid of my IB1 with the introduction of SIP credentials… But I’ll have to get glass soon and then upgrade the router infrastructure.

Yeah right. Would be valid at most as a work-around. Nevertheless, I would like first-hand information:

  1. Swisscom supports standard XY and third-party routers must install feature Z so that the third-party router works smoothly with IPv6. (“Error” with the third-party router manufacturer)
  2. The I-Büxes use a proprietary feature A to activate IPv6 and users of third-party routers must a) tilt the bowl in Kundencenter or b) can contact the hotline or c) have the temporary use of an I-Büxe activated for IPv6. (“Error” at Swisscom)

And these are already clues which [here](https://www.swisscom.ch/de/privatkunden/hilfe/geraet/internet-router/ Fremdrouter.html) - alongside others discussed in this thread - are still missing .

Still not. The specific response from AVM is recorded here.

Apart from the work-arounds already described (see above):

Does anyone have a third-party router on the Swisscom RES network that gets an IPv6 prefix without any problems or tricks? Or to put it another way: Do I have a specific problem with my third-party router, or does Swisscom have a general problem with activating IPv6 on third-party routers? Who doesn’t adhere to the protocol specification?

Could someone who has a third-party router and IPv6 working properly log the DHCPv6 sequence on the WAN port and post it here anonymously?

The main thread with my problem is in progress here. The cross-posting should target the non-Fritzbox third-party routers or the functioning IBs.

😉

Challenge accepted!?

Here as a reference is the update from the other thread other thread - even without SC router You can get an IA_PD reproducibly and quickly with Fritzbox 7583. Details are recorded there.

I can provide Wireshark traces for “correct” DHCPv6 with Ftizbox upon request.

Bunny takes revenge. You already won the challenge over there. 😁 You too: 🎖️

For everyone who doesn’t understand this. The question in Post 36 (above) was solved like this: that the frit was not understood with the BNG. The problem can be repaired with a configuration change in the frit and that this will be resolved until the next [release](https://community.swisscom.ch/t5/Router-Hardware/IPv6-nativ-mit-FritzBox/m-p /742195#M42657) may still show up on a third-party router.

4G / 5G Booster: Doesn’t support IPV6 yet, as far as I know.

Since most of my data traffic goes via booster (50-80Mbit/s down, 50 up), and only a little via copper (max. 12Mbit/s down, 1Mbit/s up), all devices (5-person Household) is significantly “slower” when traveling with IPV6 activated… because the booster is effectively no longer used. Especially noticeable when uploading.

Is there already an update regarding the booster?

A completely new solution e2e is needed. It is being worked on and will probably come in 2023. This can then handle IPv6 and UDP traffic, etc.

Since we already looked at the solution in 2019 and wanted to implement it, I can’t say why it’s taking so long. You probably have other priorities.
