ipv6 on G.Fast FTTC

dcrdev — Sun, 01 Dec 2024 14:28:49 GMT

I’ve just spoken to EE technical support about setting up IPv6 on my router. Initially, I was told that all EE customers should have IPv6 enabled, but we ended up speculating that it might not be available for G.Fast connections. Unfortunately, the guy I spoke to wasn’t certain and couldn’t provide any concrete information.

To give some context, I’ve recently transitioned from using the Smart Hub + OPNsense (dual NAT) to a setup with OPNsense + modem over PPPoE. Now, I’m trying to configure IPv6 for the first time.

This is my WAN config

This is my DHCPv6 config:

No matter what I try I cannot get it to delegate any prefix to me:

dominic@hell01-router01:~ $ sudo dhcp6c -d -D -f pppoe0 Dec/01/2024 13:42:56: extracted an existing DUID from /var/db/dhcp6c_duid: 00:01:00:01:2e:de:88:d6:00:e2:69:7e:50:87 Dec/01/2024 13:42:56: cfparse: fopen(/usr/local/etc/dhcp6c.conf): No such file or directory Dec/01/2024 13:42:56: reset a timer on pppoe0, state=INIT, timeo=0, retrans=45 Dec/01/2024 13:42:56: Sending Solicit Dec/01/2024 13:42:56: a new XID (97f5db) is generated Dec/01/2024 13:42:56: set client ID (len 14) Dec/01/2024 13:42:56: set elapsed time (len 2) Dec/01/2024 13:42:56: transmit failed: Network is down Dec/01/2024 13:42:56: reset a timer on pppoe0, state=SOLICIT, timeo=0, retrans=1061 Dec/01/2024 13:42:57: Sending Solicit Dec/01/2024 13:42:57: set client ID (len 14) Dec/01/2024 13:42:57: set elapsed time (len 2) Dec/01/2024 13:42:57: transmit failed: Network is down Dec/01/2024 13:42:57: reset a timer on pppoe0, state=SOLICIT, timeo=1, retrans=2120 Dec/01/2024 13:42:59: Sending Solicit Dec/01/2024 13:42:59: set client ID (len 14) Dec/01/2024 13:42:59: set elapsed time (len 2) Dec/01/2024 13:42:59: transmit failed: Network is down

I'm really starting to think that it isn't supported - does anyone have any experience with this on g.fast?

@dcrdev Up until recently IP6 was not available to legacy EE customers, however after another customer reported they had discovered it was now working, I also tried my old EE router and sure enough it did..

Not sure it is available in all areas or what the migration plan is. However before going any further you may be better checking with your EE router to see if it is available for you.

Then come back and let us know if you do get it working - I too am trying to work out the settings for my Asus router..

Until recently legacy EE BB was IPv4 only but in the last few days a few reports are coming in that it now supports IPv6. You can check if you are IPv6 enabled with Test your IPv6.

@Mustrum : Having enabled your router for iPv6 DHCP how can you check directly if it is enabled for you other than the above?

Re: ipv6 on G.Fast FTTC

dcrdev — Sun, 01 Dec 2024 15:42:31 GMT

@Mustrum

I plugged my EE router back in out of curiosity and it says under ipv6 -

Supported: true

Connected: false

Besides that there is not much in the way of configuration.

---

@XRaySpeX https://test-ipv6.com/ shows 0/10 which is what I would expect as I currently only have a link local ipv6 address as oppose to a global one derived from the prefixes EE should be delegating.

@dcrdev I had not used my EE router for a while, and did notice it did a firmware update soon after it was connected. It may be worth leaving yours on for a while, or overnight if it is more convenient. There was nothing to configure on mine either, it just worked.

This site is handy for checking if it has worked https://whatismyipaddress.com/

@dcrdev @Mustrum If any use this is what the EE Smarthub+ has for it's 2 IPV6 screens, was same for FTTC and FTTP attached.

Mustrum — Sun, 01 Dec 2024 16:25:22 GMT

@JimM11 my router is an original Smart Hub, and the OP will probably have the white Smart Router.

Re: ipv6 on G.Fast FTTC

XRaySpeX — Sun, 01 Dec 2024 16:35:21 GMT

Yes, @Mustrum ,but I'm asking you how you can check it directly?

Re: ipv6 on G.Fast FTTC

Mustrum — Sun, 01 Dec 2024 16:44:40 GMT

@XRaySpeX On EE routers there is nothing to configure, however there are q dew options on my Asus. The whats my IP returns your IP4 and IP6 addresses if the router is set up correctly.

Re: ipv6 on G.Fast FTTC

JimM11 — Sun, 01 Dec 2024 16:53:09 GMT

@Mustrum Have a look if this Asus is any good for your router, still have the EE Smarthub+ 1st up so not worrying about IPV6 on the XT8 yet.

Sorry, @Mustrum , I'm not asking how to configure the router. I'm just trying to know how you would see IPv6 actually in operation in anger w/out using 1 of these checker sites.

Thanks @JimM11

I found this which I am working my way through, but I need to plug the EE router back in and make a note of some of the values that don't seem to be picked up automatically.

Re: ipv6 on G.Fast FTTC

XRaySpeX — Sun, 01 Dec 2024 17:15:05 GMT

Is it such a daft Q? I just want to know a way of seeing IPv6 actually in operation on an actual connection to the Net, not just the settings of your devices,.

JimM11 — Sun, 01 Dec 2024 17:19:22 GMT

@XRaySpeX Ping the ipV6 address or DNS lookup will return IPV6 when working, think you seen it on mine when i did a ping to the BBC couple weeks back.

Mustrum — Sun, 01 Dec 2024 17:37:06 GMT

@XRaySpeX think about it another way. How do you know that IP4 is working?

There are a few IP6 only sites, so if you don't have it you won't be able to connect to them - mostly game sites.

But otherwise for day to day use you may be connected to a site via IP4 or 6 if both you and the site have both, but underneath the workings you won't really know.

dcrdev — Mon, 02 Dec 2024 12:17:02 GMT

I plugged in my EE router today and definitely not getting an ipv6 address. Interesting to see from the above that for those that do have on FTTC it's configured through SLAAC as opposed to DHCPv6 over ipv4; that was the configuration I was able to gleam from other forum posts, but maybe it's different for FTTP.

So I guess it's not rolled out yet widely to FTTC customers 🤔

Would be nice to get an official statement from EE on the rollout for FTTC, ipv6 in general seems to be shrouded in mystery for EE.

Mustrum — Mon, 02 Dec 2024 14:10:34 GMT

@dcrdev iy maybe that they are not going to bother with G Fast customers as it will soon disappear?

Or maybe it is a Geographic thing, the other customer appeared to be in Kent, I am in Dorset

Or perhaps it a Fibre Only thing.

Re: ipv6 on G.Fast FTTC

dcrdev — Mon, 02 Dec 2024 15:39:09 GMT

Yeah maybe

I'm holding onto G.Fast for dear life, at the moment because they have discontinued it, if I want to re-contract I lose g.fast and am down to 60mbps from 150, no FTTP in my area.
