IPv6 Protocol

Ardua · Nov 13, 2011, 11:54:42

My router is IPv6 compatible. Is the IDNet IPv6 provision Native IPv6 or does the connection have to be established using an IPv6 to 4 tunnel? Thanks.

Rik · Nov 13, 2011, 11:59:20

Sorry, no idea, but others will have.

.Griff. · Nov 13, 2011, 12:00:55

I thought it was native but I could be wrong.

Thanks Guys. With a little bit of 'Google is my friend', I think that I now understand what is going on. The router log shows a IPv6 connection with an IP address; however, when I run an IPv6 test it comes up as IPv4 only. It would seem that I need to use parts of the IP address to set up a Local Host - unfortunately, Google translation of German websites only adds to my confusion.

Steve · Nov 13, 2011, 12:17:35

It's native IPv6 there's at least two of us using IPv6 on the 7800N

Rik · Nov 13, 2011, 12:31:43

Interestingly, you still show an IPv4 address in the forum, Steve.

Simon · Nov 13, 2011, 12:33:28

Presumably, that's because the forum isn't IPv6 compatible yet?

Rik · Nov 13, 2011, 12:35:01

Well, that's the interesting question, isn't it - what happens when only an IPv6 address has been issued...

Steve · Nov 13, 2011, 12:36:44

That's because the router provides both IPv4 and IPv6 addresses to the client - Dual Stack. I would not be able to access this site via IPv6 as it has no IPv6 address

Steve · Nov 13, 2011, 12:40:35

Smf is not IPv6 compatible, if this site had an IPv6 address I would show as 0,0,0,0 I believe. Most browsers preferentially connect via IPv6 if it is available.

Ardua · Nov 13, 2011, 13:40:58

Now look what I have started

Unless you've also enabled IPv6 on the computer then that's how it will seem... there's no NAT (usually) on IPv6 so an IPv6 connection is made to the IP of the computer, not to the router as in IPv4.

You'll need to enable IPv6 on all PCs that you want to be IPv6-capable, the router will dish out addresses using DHCP from the (slightly huge) pool that IDNet provide.

If you're using Windows then someone else will have to explain how to enable v6, I use a Mac!!

Thanks. I am exclusively Mac. I have an IPv6 router address showing in my router log. I have now looked at the Apple Support guide on IPv6 enabling but I am still confuses ( a function of advancing years). What do I use for the IPv6 address, router address and prefix length (received from your network administrator or ISP)? Many thanks.

Steve · Nov 13, 2011, 20:19:12

On SL and Lion (as I'm not using TBB BQM with IPv6) my IPv6 address is set to automatic via network preferences.

Bill · Nov 13, 2011, 20:52:40

@ Ardua:

As Steve says, just set it to automatic in netprefs and let it get on with it.

I actually use fixed v6 IPs on the iMac and MacBook, but I cheated to set them... as long as they were fixed I didn't care what they were, so I got them from IDNet using "automatic" and used those values to fill in the slots for "manual"- worked a treat

mervl · Nov 22, 2011, 10:01:26

I've been (slowly) acclimatising to the vagaries of a Fritz!Box and IPv6 compatibility is one of its treats. However, I assume using IPv6 is likely to give me trouble with the banking and (not the majors) shopping sites (and Citrix remote access software) I rely on, and kick off my more ancient Nokia and Blackberry semi-smartphones and one ancient XP laptop (rest are Vista with use TCP/IP over IPv6 already ticked, so seem OK), and it's therefore a

-no until I have to?

Lance · Nov 22, 2011, 10:17:48

As long as you don't go ipv6 only you'll be fine. I think all routers at the moment offer dual stack do that if you go to a website which is ipv4 only there isn't a problem. Likewise for devices which only support ipv4.

What IPv6 FB7390 settings are you using please? I have tried just about every combination and whilst I can get an IPv6 IP address (as shown in 7390 log), I cannot get a connection. I am using Mac OSX Lion and Automatic is set in the appropriate box in Network Settings. Many thanks.

mervl · Nov 22, 2011, 14:53:12

Ardua

You're one better than me as I can't get an IPv6 address: mine comes up with "IPv6 internet connection error Prefix assignment with error because of 0" which I assume is an unspecified fault. What are your IPv6 settings?

IPv6 Enabled plus Native IPv6 and the other recommended settings. Once Apply is selected, the box re-boots and I get an IPv6 IP address in the System Log but the IPv6 button (under the IPv4 button) does not show an IPv6 connection. I confess that I am now more confused about IPv6 than I was a week ago!!

mervl · Nov 22, 2011, 17:10:10

Sorry for adding to the confusion.

Same settings and result here, with the exception that my FB doesn't reboot on Apply (only re-authenticates) and I don't get an IPv6 address. I've now rebooted manually but it made no difference. I have the "unlit" IPv6 button on the homepage, so it looks as though the router is set up.

I do wonder from another post above, though, if it takes several hours for IDNet's server to issue the IPv6 address? We're thinking it's a router problem, but could it be a problem at IDNet's end with the issue and authentication of new IPv6 addresses?* I see from whirlpool.au that others have reported the same log report; but there's nothing about what to do about it, as far as I can see.

*EDIT: could this be worth thinking about, I noted that TBB's tester reported several timeouts when checking IDNet's IPv6 compatibility?

mervl · Nov 22, 2011, 20:24:16

Ardua: No responses here, so I've sent an e-mail to IDnet support tonight asking them to let me have manual IPv6 settings for my account. I'll let you know how I get on.

Steve · Nov 22, 2011, 22:59:00

Sorry we can't offer any more advice, the two of us I know that run dual stack just enabled IPv6 in the router,(7800N) we both use Macs and with NIC setting to auto the IPv6 address is served to the client. No settings were requested from IDNet the only thing that I can add that if you have an LLU connection to IDNet IPv6 that has not been enabled yet. There's some tick boxes on the 7800N one for enable IPv6 along with an input box for requesting the IPv6 address automatically i.e. '::" and one for the IPv6 DHCP server (although I've not worked that function out yet). Your client has to have an IPv6 address for it to be visible as there is no NAT in IPv6 so the router address is irrelevant for TBB tester and IPv6Test.

Reading this http://www.avm.de/en/Extern/files/ipv6/IPv6_Technical_Note_en.pdf

I think you need to set the box to get the IPv4 address first , this is the method the 7800N uses, I think Bill and myself have both failed with the second option

i.e.

In Which Order Are IPv4 And IPv6 Negotiated?

This depends on the setting in the FRITZ!Box:

In "Always use a native IPv4 connection" mode, a native IPv4 connection is established first. If a 6RD gateway was learned through DHCPv4, a 6RD tunnel is established. Otherwise the device will try to establish a native IPv6 connection (dual stack).

In "Always use a native IPv6 connection" mode, a native IPv6 connection is negotiated first. If an AFTR gateway was obtained via DHCPv6, DS Lite will be used for IPv4. If no AFTR gateway is known, or it was not possible to establish the native IPv6 connection, native IPv4 will be used.

mervl · Nov 23, 2011, 09:28:09

IPv6 has been connected on my Fritzbox since 0912 this morning (Wednesday).

No changes or resyncs since yesterday on my setup, so I wonder if IDNet have done something at their end after my e-mail? Dunno why I've done it though, apart from sheer devilment! edit: yep, Simon's confirmed my account was originally set up without an IPv6 allocation.

Steve: sorry didn't see your post! Thanks for the help: I have your second option "always negotiate IPv6 connection", as I don't appear to have the option to try IPv4 first amongst the IPv6 settings despite what AVM's guidance says. I think Ardua has the same settings as me, hopefully now with the same result. At least I can still reach this page, so there's hope!

Steve · Nov 23, 2011, 10:27:57

I did post late and you confirm that you had no IPv6 address allocation previously which I suppose is a good enough reason for it not to work.

mervl · Nov 23, 2011, 10:36:39

The obvious reason I think Steve (apart from to this idiot who managed to resync the router 16 times yesterday in trying!). An error code 0 = no response is perhaps pretty obvious really, so I blamed the router!!

I think it used to be what techies called Error Code 16 wasn't it: those that occur some 16 inches in front of the hardware?

Ardua, just wondering: does that explain why you can get an address but not, seemingly, the prefix assignment, so no connection?

As I have been with IDNet for over 5 years I suspect given your experience that this is something that Support will have to take a look at. I have just enabled IPv6 using all the Automatic/recommended settings and I have a line in the Log which states ' IPv6 connection established successfully. IP address 2a02 ..........' Unfortunately, the online monitor still says 'No IPv6 connection'.

To help others, and to promote the use of IPv6, perhaps IDNet need to offer some IPv6 on its website (or a sticky here perhaps)? Just a thought.

Whilst I wait for a response I will keep an eye on the Carillion team that has just appeared to install a FTTC cabinet at the top of my road.

mervl · Nov 23, 2011, 11:41:28

Ah, my log shows two lines both of which say IPv6 connection successful:
1. then gives me the IPv6 address
2. the next gives me the IPv6 Prefix (where I had the error saying O, previously).
The homepage button is then lit.

You appear to be lacking the Prefix necessary for connection.
In the settings page a box with details of the connection now appears below the tick box to activate IPv6 (previously it would appear briefly when I clicked Apply and then disappear).

My FTTC cab appeared in April, and the service was available in mid-July (two weeks from the advertised date, and about 6 weeks after the electricity was connected - which is the bugbear). There's a useful response from Philippe on the whirlpool.au UK thread regarding the VDSL/CLI issue (which I haven't tried yet after my forcing resyns yesterday - I'll give the Box a well-earned rest). If you don't get any problem I'd be interested since it'd then be a PTSN line quality issue.

Ardua · Nov 23, 2011, 14:07:07

Thanks Mervl. Thanks to Simon at IDNet I, too, now have IPv6 connection with all the router settings set at recommended. Not sure what difference it makes, but at least the Fritz!Box is performing as the makers intended. Rik - I still think that it would be helpful to other IPv6 adopters if there was a sticky advising IDNet customers to contact Support requesting IPv6 allocations.

Steve · Nov 23, 2011, 15:17:36

Re IPv6 allocations sticky this would be contrary to the current advice and past experience i.e.

http://www.idnet.net/news/article.jsp?id=84

I think if the above is not the case and we need to discover why the two of you had no allocation, then yes it should be done.

mervl · Nov 23, 2011, 16:55:25

I know it's a big bother, but how about a guide on the IDNet pages to IPv6 and what IDNet offer, which will surely become increasingly a good selling point for the service (and good PR)? It could explain that although router setus ups are different - and the first thing is to follow your router guides, if having done so you find you can't get an address and prefix, to contact support to check IPv6 allocations are available on your service?

Steve · Nov 23, 2011, 16:58:43

I think if enough interest is shown we could probably write a sticky guide and pull all the IPv6 posts together.

As more and more routers come out with IPv6 compatibility, then people will want to fiddle. Not everyone who posts here, myself included, has a detailed knowledge of the subject. When I asked my daughter about IPv6 (and she has a degree in Computer Science) her answer was 'I will have to ask our IT technicians'!

As an aside, when I run the various IPv6 tests they all come up Green. However, when I try to load the TBB IPv6 test page it comes up with an IPv4 connection. Selecting IP6 Native in my router settings changes nothing. Aussie forums suggest that this is a dual-stack related issue. IPv6 only websites load normally.

Steve · Nov 23, 2011, 17:18:22

Bill may know the TBB answer but it sounds to me like your browser is connecting to TBB via IPv4 (most browser these days will try IPv6 first on an IPv6 enabled connection)

Can you try http://ipv6.thinkbroadband.com/ and see if that works?

The link works fine. There is a suggestion at Whirlpool that this is not a router issue. The 'problem' - if there is one - is within Mac OSX Lion. See the comments from Simon Hackett at:

whrl.pl/RcZ0zX

Edit: If I then click the IPv6 box on the page it then shows that I am connected via IPv6.

2nd Edit: I have just 'Googled' TBB on an IPad and clicked the IPv6 box and it shows an IPv6 connection. It would appear that IOS5 operates differently from Mac OSX Lion.

Steve · Nov 23, 2011, 19:01:57

It's certainly not that simple anymore especially if the OS is going to decide what's best for you. I guess that's a good thing as there's no point waiting for a page to load if there's a quicker alternative. It's seems Lion will also cache data and decide whether IPv4 or IPv6 is best for you.
