IPv6 - EE Full Fibre (Same as BT?)

[ShutterbugLozza]

Hello everyone,

As someone who works in IT, I thought it might be worth learning about IPv6 and as a starting point, I've been considering implementing it on my home network. I'm currently utilising a Ubiquiti USG 3 and have it connected to EE Full Fibre. It's configured with IPv4 on the WAN port, using the EE standard username and password, which works perfectly.

My question is whether or not EE has implemented IPv6 on the FTTP / Full Fibre network and what the appropriate details are? The USG 3 requires the following settings:

I've read some alternating information on this in different places, some suggest that EE has no IPv6, some say only on the Mobile Network and others where it uses the same connection settings as BT Full Fibre - which I've tested (DHCPv6 and /56 as the Prefix delegation size) to no avail. Wondering if there's any EE specialists who might have some insight on this?

Thanks in advance!

@MossDev   if you are anywhere near the south coast you are welcome to come along and have a play with my router.  Either my own Asus, or the EE supplied one.

I did have another try earlier, I know they are getting the PN DNS routers ready for IP6, but nothing detected. Will have a look on the BT forums to see if they have any specific IP6 settings I may have missed.

Do let us know how you get on though.

Perhaps @bobpullen  may be able to give us a little more info.

@Mustrum , thanks for the offer, I am actually just about to drive down to Brighton for a few days, but I will be spending the time with friends and family.

I would really like to get to the bottom of this, do you use Discord or any other chat/screen share apps?

I would be up for having a conversation and seeing how far we can get setting this up before I end up with a service I can't use.

Setting up the Asus router would be a lot easier than the EE router, if that is an option. 

Do you have any Linux devices we can test with, like a Raspberry Pi... Linux can be easier to debug than Windows.

If you are up for experimenting let me know and we can start chatting somewhere.

@MossDev   as it happens I am 3hours/110 miles west of there.

I have found a few posts on 3rd part IP6 setup on the BT Network, including this one for an Asus:

so will have a play. 

I don't have any Linux devices, the link above should have enough info to see if IP6 is available.

The EE issued hub (assuming it's a recent model) isn't really a factor; as far as I know, the Smart Router/Smart Hub will already be configured to support dual-stack IPv4/v6 out of the box. In order for that to be any use though, it needs enabling out on the network.

My understanding is that this is not the case for the vast majority of EE-provisioned broadband customers (like @XRaySpeX has advised). A lot of the broadband network architecture is common between BT, EE and Plusnet, but there do exist differences that mean IPv6 is not natively supported across all of the brands.

I have a suspicion it won't be too long before you start seeing some newer EE broadband customers coming online with IPv6 delegations, but for now, I think it's fair to say it isn't offered.

@MossDev be interested to hear if you find this isn't the case.

Hi All,

Sorry it has been such a long time. I finally moved in to the new house and have been testing my new EE full fibre.

TLDR: I have full IPv6 support

The long version:
I have been testing various services, http, https, different servers, forwarding domains etc.

EE have a bit of a strange naming convention for the IPv6 port forwarding, they call this Pv6 Pinholes, I have never heard it referred to like this. However, once you know what ports you want and the devices global IPv6 address, it is very easy to set up.

Another weird thing is every Ubuntu device seems to get multiple global addresses, one of my devices has 8 (most are 64 prefix length, and a couple are 128). And unless you come in on the right address, the router blocks the request. To get the correct IPv6 Address I just run  `curl icanhazip.com` and then check the returned IPv6 address is on the list of available addresses. Using that address has worked every time.

I think all of this will be much simpler using a better router, I will be trying some more coomercial gear of the next few weeks and I think I should be able to access each device using any of the addresses they are given, which means I can start using the short address (128 prefix). I have only got this to work on a single device so far, but that short address is also the one shown in the router config.

Let me know if any of you have any questions. Also I would like to hear if any of you can get IPv6 added to an older line.

Thanks.

@MossDev  glad to hear you are up and running, and it seems lots have changed in a few short months for those on the new network. 

Still no change for me on the old network though..

Just switched to EE FTTP from BT FTTP. I did not have to change any settings, and IPv6 is working just fine. I'm using an Edgerouter 4 in place of the BT or EE supplied hubs.

Yes, @MossDev , since you posted in Aug. a lot has happened. EE New Full Fibre BB was introduced in about Oct. which does support IPv6 & you have been put onto that.

Could I ask what settings you are using please? I have just moved from BT GFast to EE FTTP (900) and while the PPPoE username/password combo from BT still works, my IPv6 settings throttled my speed so I disabled IPv6 for now.
I was using  Connection type PPPoE - Share the same PPPoE session with IPv4 - Prefix delegation size 56

[MossDev]

Hi @HSF69 

My prefix length is 64

I noticed a lot of people on the old network say the prefix is /56 but that does not work for me on this new system. The EE router came with /64 as default in the settings.

Another thing I had to change on a 3rd party router was Allocation mode, I had to set this to stateless.
