IPv6 WAN interface not getting prefix, only single IPv6 address

earlish · Jun 20, 2017, 2:10 PM

Hi All,

I recently purchased an SG-2440 for my new internet service which was supposed to be 100/100M (best effort)

The IPv4 is working fine until 6pm-2am where it gets completely congested and I only get 500kpbs down although I still get 60-80Mbps up

I called the ISP and they activated IPv6 on my account. My ISP is So-net with infrastructure by Docomo/Flets-East Hikari. IPv4 is with a PPPoE tunnel and IPv6 is IPoE apparently.

I would appreciate if someone could check over my setup and let me know if I am doing something wrong, or I should get rid of my ISP after just 3 days and suck up the early termination penalty.

With a PC connected directly (bypassing pfSense) I can pull an IPv6 address with a 64 subnet and IPv6 traffic is around 90/90M;

$ ifconfig en10
en10: flags=8863 <up,broadcast,smart,running,simplex,multicast>mtu 1500
	options=10b <rxcsum,txcsum,vlan_hwtagging,av>ether 10:dd:b1:e3:e7:2d 
	inet6 fe80::180e:8cbb:d5c8:2865%en10 prefixlen 64 secured scopeid 0xb 
	inet6 2409:10:a860:3000:4ff:4101:c878:648b prefixlen 64 autoconf secured 
	inet6 2409:10:a860:3000:88ab:4169:1bb5:dcf6 prefixlen 64 autoconf temporary 
	nd6 options=201 <performnud,dad>media: autoselect (1000baseT <full-duplex,flow-control,energy-efficient-ethernet>)
	status: active</full-duplex,flow-control,energy-efficient-ethernet></performnud,dad></rxcsum,txcsum,vlan_hwtagging,av></up,broadcast,smart,running,simplex,multicast>

The (lacking) IPv6 information on the ISPs website says that a /56 of address space is available per customer. While other pages are indicating that a /60 is allocated if you have a VoIP service and a /64 if you don't have VoIP. At this stage I would be happy just to have a /64 and use that for just 1 LAN interface.

Now the problem appears to be that the WAN interface on the pfSense is only being allocated 1 IPv6 address instead of a /56 prefix and it is unable to then delegate /64's to my LAN interfaces.
I am quiet new to the IPv6 world, so please correct me if I am not understanding things correctly, but this looks like the prefix delegation is not working at all?

I have configured the IPv4 as PPPoE, IPv6 as DHCP6 with the LAN interface IPv4 Static, IPv6 as Tracking.

If I configure the WAN interface as a 6to4 tunnel, I can get the proper prefix on the WAN, and the LAN interfaces work as expected with Tracking. But I guess this completely defeats the purpose of having IPv6 and all my traffic will still be on the congested IPv4.

I have also tried factory resetting and configuring just the WAN interface with the same results.
My setup is as follows, and I have tried pretty much every combination without any success.

If your V4 is PPPoE, set the WAN v6 to DHCP and tick the box 'Use IPv4 Connectivity as parent interface.

The dhcp6c client needs to talk over the PPPoE connection.

Set LAN IPv6 to track the WAN interface and you should get it working.

When I set the 'Use IPv4 Connectivity as parent interface' I just get a local link address on the WAN interface;

Something is definitely wrong, if you have selected use parent interface then the line in your logs that says this:

Jun 21 08:32:51 dhcp6c 16741 send solicit to ff02::1:2%igb0

Should be showing something like this:

Jun 21 06:43:01 dhcp6c 43299 send solicit to ff02::1:2%pppoe0

Note the pppoe0

In either case, dhcp6c is sending solicits but is getting no response from the ISP.

The settings should be like those I have shown in the attached image.

I factory defaulted the pfSense and I put the same config as yours, but still no IPv6.

Does this mean dhcp6c is getting a response, but there is no prefix?

Guest · Jun 21, 2017, 12:33 PM

Indeed it does, they are not offering a prefix.

earlish · Jun 22, 2017, 3:37 PM

Thanks for that,

So I'm wondering what does my ISP expect I can do with 1 IPv6 address (/128 ?) is that some kind of joke?

How can the ~~crap~~ consumer grade routers work in this case? Some kind of IPv6 pass-through/bridge?

Sorry I'm not so familiar with IPv6, but I thought it was supposed to get rid of all this NAT nonsense.

awebster · Jun 22, 2017, 3:42 PM

The sad truth is that many ISPs don't have a clue either and are hopelessly stuck in IPv4 mentality.
Exercise your opinion with your wallet.

Guest · Jun 22, 2017, 3:44 PM

Best thing to do in the first instance is to email your ISP 2nd tier support and ask them what exactly they supply IPv6 wise.

earlish · Jun 22, 2017, 4:00 PM

Well it looks like I will be exercising my wallet, after I cancel this ISP after just one week and I have to pay the cancellation penalty. Their IPv4 is absolutely completely useless and going to IPv6 probably won't solve the problem as a lot of stuff is still in the IPv4 domain.

I just wanted to confirm that there is nothing silly I am doing with pfsense that would prevent me from getting IPv6 to work properly before I complained again to the ISP.

Cheers.

earlish · Jun 25, 2017, 3:51 PM

So it turns out if I use a v6 username (i.e. user@v6-isp.jp instead of user@isp.jp) for the PPPoE I can get a /56 prefix assigned. But by doing this I do not get an IPv4 address.

I did manage to get both IPv4 and IPv6 to work by adding another PPPoE tunnel on another interface. (OPT1 in my case)

So now my question is; do I need to use 2 interfaces (WAN and OPT1) to use 2 PPPoE tunnels, or can I use 2 PPPoE tunnels on 1 interface?
I couldn't find any information about this but I'm sure there is a better way than what I'm doing. Or is using 2 PPPoE tunnels just not the usual thing to do, as I did come across this thread https://arstechnica.com/civis/viewtopic.php?f=10&t=1378151

@earlish Hi,

Do you still use pfsense?
I'm facing the same problem as you using AsashiNET provider.
Only the WAN gets the prefix, LAN It is not getting anything.
Please let me know if you found a solution because my provider doesn't support PPPoE for IPv6.

Thanks in advance.
