Open IPv6 Issues / questions

Le,

from now and the next 13 hours would be no problem. Same goes for the next few days.

since i am now on holidays and got a little bit more time on my hands:

- the IPv6 patch from Le is working great, 12 days of connectivity here on my testbox via ipv6 and pppoe

Completly unrelated to IPv6 via PPPoE: Been trying to get IPv6 working on a friends "Deutsche Glasfaser" Connection. They are using 6rd which is kind of evil i think, but we managed to get it working on this WAN Interface, also with additional addresses and WAF/VPN working!. What is not working is his clients getting "out". We tried various things (including using masquarading which normally works), a traceroute would always end at the IPv6 of his internal interface. I suspect an addition route is probably missing. Anybody who can point me in the right direction here please?

In the 9.502 changelog I don't see any IPv6 related changes, so I assume that the patch didn't make it in time?

Hi SanderRutten,

   No it is not yet in the release since currently it is in QA cycle. Will let you know ASAP. Thanks for helping us out!

i noticed in 9.503-4 there is a fix:

[Network] Prefix Delegation does not work correctly during a PPPoE reconnect

is this the implementation of this patch?

Yes, it is.

Thanks for your help and patient!

Hello Le (And maybe Ben

I just figured something out, but not sure if it is related to the original problem here.
I think I can sum it up to: Network definition "Internet IPv6" is unresolved. Therefor I'm unable to create a (working) firewall rule to "Internet IPv6".

Probably because it is not bound to an interface, but I can't assign an interface. In my WAN's interface defenition it is set as "IPv6 Default GW".
I found out while trying to thighten my home security, it was quite open from internal network to the outside world. 

First I had rule #1 and #3 combined, as well rule #2 and #4. But while trying to understand what happened I split them both in an IPv4 and an IPv6 rule. So now I have:

As you can (hopefully :)) see: The small '6' is not displayed in the Internet IPv6 icon, but it is for "Any IPv6". And for IPv4 it also shows the little 4 in the icon.
What I expect to happen is while surfing via IPv6, that rule #3 is being used. Instead it always used #4. 
For IPv4 it works like what I was expecting. 

When I don't enable the Any IPv6 rule, all traffic is dropped by the default rule.

Any ideas if I can fix this myself?

Hi SR,

   Good to hear from you.

   OK, I am not sure what the problem is. Here is the what is needed:

   1) I have a script "get-data.sh" which will collect UTM system data. I need, somehow, to give this to you; Please let me know how I can send it to you. Thanks

   2) Do a tcpdump on the interface

   3) ./get-data.sh  ipv6

   4) Collect the data from step 3 and step 2 above

   5) Send me the collected data

   Question: Do you know how to turn tracing on Iptables? If yes, please turn it on and capture the iptables trace as well

    Good luck!

ipv6 works strange with rules, any ipv6 -> any -> any ipv6 / internet ipv6 will not work as expected.

Putting an Interface with a /64 IPv6 Subnet will not allow it "per se"

would still like some extra options to hardlock the prefix gotten, my isp sometimes reboots their router and unfortunitly ipv6 comes up last and the UTM reacts funny (Le has some info on that when he has some time on his hands in the future)

otherwise i am happy UTM is this far thanks to LE!

Hi Ben,

according to my daily report IPv6 traffic is passing the UTM.

Thank you for your assistance.

Update. blocks facebook with tunnel fails and fails to fall back correctly, strange when using native and google home page takes considerable time to load. All fixed when ipv6 disabled and dhcp ipv6bon internal interface disabled.
