Open IPv6 Issues / questions

Hi Ben, please see my answers inline below:

Ben said:

- will the fix for issue NUTM-7187 be included with 9.5?

 [BL]: The fix for NUTM-7187 is not included in this current UTM 9.5 beta version. We are actively working on the fix right now though, so as soon as we have a confirmed fix it will be included in a subsequent release.

- is there a fix in the works for IPv6 Connections where the WAN Port is supposed to use an address out of the delegated prefix? Currently users of such ISPs do not get any IPv6 address. (for esxample KPN netherlands)

[BL]: This should be supported today, unless the ISP is doing both stateless & stateful. Is that the case for you? If so, we are fixing that as part of NUTM-7187 as well.

- what about the ability to change/edit the UID for IPv6 Delegation Requests?

[BL]: Unfortunately this isn't part of this 9.5 release.

- what about long standing feature requests such as 6tunnel integration, lets encrypt - is that on the roadmap? Users, myself included had high hopes for 9.5 but this seems to be more than a maintance release.

[BL]: Lets Encrypt is on our current roadmap, but it's mainly planned as a WAF feature. As for 6tunnel integration, it's currently not planned for any specific release.

 

thank you in advance.

 

Hi Bobby,

Normally the ISPs router will then request /48 prefix and use a /64 from that prefix for the wan interface and a /64for the lan interface. So there are no other global ipv6 addresses than the ones from that /48.

On the Sophos UTM, in my case I will only receive a link local IPv6 address via PPPoE. Using a tcpdump I have verified the UTM is not sending out a prefix request after the PPPoE has been established. Is it waiting for a advertised IPv6 address for the WAN interface first before it will do this? Because in this case it will never get it... And thus a IPv6 prefix will never be requested.

If you want to have a look at my Sophos VM, or need some tcpdumps of the PPPoE setup let me know!

Hi Le,

Sorry for the delayed reply, has been quite some busy days at work last few days so I haven't had time to capture my switch port yet. Do you still want me to do that?

And about reconnecting my connection: Go ahead! Even multiple times if needed.

Thanks a lot SanderRutten,

    Thanks for your help.

    No need to do mirroring.

    Since no PD, hence no traffics (outbound is OK, mirroring will show this. However, inbound is not since DSP does not know how to route).

Hi Le,

1) I will send you a private message with login details of the system. Go ahead and troubleshoot on it. You can initiate some reconnects if needed.

2) With the static route issue I meant the default route. So only one issue :)

Nice! Thanks for tell us it.

Hi Rene,

   Thanks so much for your help and also for letting me debug the system.

   The reason for no default route on your system is that no router responds to the RS request on the ppp0 interface.

   The system (fe80::2a31:52ff:fe59:9fa6) on the other end of ppp0 connection does not respond at all to RS on ppp0. Also, it does not send out

   regular RA. So no default route for ppp0 is a reasonable thing.

   But this system (....:9fa6) serves as DHCPv6 server, i.e. it will dish out PD if request.

   UTM's behavior wrt to "no default route" is correct.

   Will update more tomorrow.

   Thanks Rene. Your help is much appreciated.

Edited: rdisc6, radvdump can be used to send out RS on ppp0 and see what happens. Thx.

Hi Le,

Thanks for the efforts troubleshooting. I indeed already noticed that there are no RAs in my situation. Even with the capture I made when using the ISPs supplied box it did not send any RAs

# rdisc6 ppp0
Soliciting ff02::2 (ff02::2) on ppp0...
Timed out.
Timed out.

No response.

OK and Thanks Rene.

Can I use your system for another day or two? Thanks.

Sure no problem.

Hi Le,

I see you have been rebooting my UTM a few times the last days and assume you are still working on the issue? Do you have any updates? Could you share with us what you are working on?

Regards,

René

Have 6 tunnel and native on UTM waiting for 6 tunnel and native on XG.

Native 6 is no longer a high priority because the progressive ISP was taken over by a regressive ISP.

But, when the NBN arrives I might change ISPs to one that assigns native 6 to home users.
