Singtel 5gbps ipv6

[xiaofan]

If you use a more powerful device which does everything in software (eg a pfsense box etc) then you would see only a very small performance difference (~1%) from the tunnel. Same if you were to use a device that can do the tunnel in hardware.

This is in line with what I see with 6rd tunnel on my virtual OpenWRT router running on Intel N100 mini PC. The performance seems to be okay.

I also tried 6rd on the Asus RT-AX86U (Broadcom BCM4908 CPU, quad core Arm Cortex A53 at 1.8GHz) and I think the performance was also okay. Same for Asus TUF-BE6500 (Qualcomm IPQ5322 CPU, quad core Arm Cortex A53 at 1.5GHz, with one NPU at 1.5GHz as well).

I have not done the real benchmark testing though. I will try to carry out some simple speedtests using iperf3 or OOkla Speedtest with IPv6 enabled test server. M1 OOkla SpeedTest server is IPv6 enabled, but then Singtel has no good connection to the M1 SpeedTest server using IPv6 (no problem with IPv4).

Just wondering what kind of devices can do the tunnel in hardware. Thanks.

Sorry but can anyone share what the 6rd settings are for SingTel? Tried to google but not sure if the info os up to date. TIA!

Singtel IPv6 specific info.

1. 6rd IPv6
1) /128 for WAN interface, routed /64 prefix for LAN interface
2) Singtel does not provide IPv6 configuration for Singtel ONR users. But you may be able to configure 6rd by yourself with the ONR.
3) For ONT users, you should be able to configure 6rd by yourself.

IPv6 Protocol: IPv6 - 6rd
6rd Runner Type: Manual.Configuratuon
IPv6 Prefix: 2400:d803::
IPv6 Prefix length: 32
Border Relay: 6rd.singnet.com.sg (202.166.127.6)
IPv4 Address Mask: 0

Or:

6RD Prefix: 2400:d803::/32
6RD Border relay: 202.166.127.6
6RD IPv4 Prefix length: 0

If you want to use SIngtel IPv6 DNS severs, you can use the following. But you can use other IPv6 DNS servers as well.

IPv6 DNS Server 1 : 2400:d800::1
IPv6 DNS Server 2 : 2400:d800::2

2. Native IPv6, deployment on-going from Nov 2023, still not fully deployed as of Nov 2024
1) /128 for WAN interface, routed /56 prefix for LAN interface

2) Singtel does not provide IPv6 configuration for Singtel ONR --> you have to request through Singtel and the backend team needs to enable native IPv6 for you -- you can not configure native IPv6 for the ONR by yourself.

3) For ONT users, you should be able to configure native IPv6 by yourself (DHCP-PD) on your router.

The only hardware i'm aware of is highend cisco stuff, which is intended to aggregate a large number of user tunnels rather than act as an endpoint. I doubt any manufacturer would implement hardware support for tunneling as it's only meant as a temporary measure when the physical equipment is far too old and EOL to implement native v6. In those cases the throughput is going to be very low anyway so even a cheap embedded CPU has no problem.
For anything using technology less than 20 years old, v6 will be natively supported by any of the major vendors.

I connected my ASUS GT-AX6000 to the bridged LAN5 of the Singtel ZTE F8648P ONR.
Internet works.
IPv6 6rd works.

My conclusion: either IPv6 6rd does not work on the TP-Link HB810, or i do not know the exact settings for it to work.

how the hell did you bridge your lan 5?????? Or are you behind a double NAT?

Now it is strange, it can be very simple, yet some people can bridge but some other users just can not bridge using the same method.

For me I was not able to bridge the Singtel issued ZTE F8648P ONR for more than two months (from 12-August-2024 to 24-Oct-2024), then suddenly on 25-Oct-2024 I can bridge the ZTE F8648P ONR, no change in the bridging method and no change in the ONR FW version. Very strange.

Did you log in the super-admin account?

User name --> support
Password --> reverse of the root password printed on the ONR.

Hardware Version V2.1
Software Version V2.1.10P5N19
Boot Version V2.1.10P10N5

Once you log in, click "FastSetting" on the top right to access the briging page. Whether you can successfully bridge the ONR is another story. I could not do it previously but a few days ago I was able to bridge the ONR. YMMV.

Omg, I can see the setting!! Does it really work? And can I have the other ports unbridged so that I can use them as access points? Or will the rest of the ports become useless ?

It may or may not work for you. You can try it. No risks here.

Make sure your router connected to LAN 5 is in Router mode and not in AP mode. Disconnect other devices from LAN1/2/3/4 to to play safe (no need to disconnect Singtel TV box if you have any).

Then bridge LAN 5 to see how it goes.

If bridging fails, then you will immediately lose internet access. Uncheck the checkbox to recover.

If it is a success, your router will get a public IPv4 address, you may need to reboot your own router. The rest of the ONR LAN ports become useless for internet access in this case (but can be used for Singtel TV).

But if you want to take risks, you can bridge one more ONR LAN port (only up to 1Gbps) and connect another router. DO NOT blame if you lose your internet access for 24 hours if you are not careful in that case, especially if you play with changing the router.

This is crazy, and it's confirm not double NAT? I don't have time to configure tonight, maybe next week. Now Im thinking twice about getting another telco for my place if this is the case haha, they said the ipv6 is slowly rolling out.

oh ya, where do i plug my mio tv then??

I have updated my reply. No Double NAT for the router behind bridged ONR LAN port.
Singtel TV box --> unbridged ONR LAN port

Last time I was always with Singtel mainly because of stability, but also partially because of the ONT trick --> you can use VLAN capable switch to split the connection into two and get two public IPv4 addresses from Singtel, essentially dual 1Gbps plan but the combined bandwidth is still 1Gbps.
https://forums.hardwarezone.com.sg/threads/working-singtel-vlan-settings-with-tplink-sg108e.5746952/

For Singtel 2Gbps users --> they can also have two public IPv4 addresses from Singtel, after bridging of the SingTel GPON ONR, the bridged port will have no Double NAT, the unbridged ports will still work for interne access and Singtel TV (if Singtel has not changed their backend), essentially become the Singtel 1+1 Gamer bundle plan, without the bundled RT-AX86U router and the WTFast gaming VPN.

There are quite some WC 2.5Gbps plan users who also do the same thing, bridging one port of the GPON ONR. One user even bridges two ONR LAN ports and use Dual WAN Load Balancing to work around the 1Gbps LAN port limitation of the GPON ONR.

this is amazing, i hope they dont take away this access after a while.

Have you confirmed there is no native v6 in your area? It seems they are rolling it out gradually so it should be available at some point.
Routers have much better native support, tunnel support is generally not well tested and might not work at all, it's also likely to be slow and will restrict you to a single /64.

I also tried changing the IPv6 settings from 6rd to:
DHCPv6
Auto
None of which works.

In the TP-Link HB810, under Advanced > Status > IPv6, i can see the IPv6 WAN IP 2400:d802:2c18::xxx
And the LAN IP 2400:d802:2cc4:ac01:b219:21ff:fe76:xxxx.

On my PC, i also can get the IPv6 LAN IP 2400:d802:2cc4:ac01:7f54:4386:e330:xxxx

But IPv6 internet does not seem to work - i cannot ping to ipv6.google.com. Any IPv6 sites like ipv6.google.com does not load.
test-ipv6.com shows "No IPv6 address detected".

However, normal IPv4 sites like www.google.com load fine.

If i disable IPv6 in the router or on my PC's TCP/IP, internet works.

As i mentioned, if i use my ASUS GT-AX6000, IPv6 6rd works fine.

Looks like that model of router is just broken, you could try looking for a firmware update or just use it as a dumb bridging access point alongside the asus.

Does native DHCPv6-PD work on the asus? it should assuming your area has been upgraded already. Routers generally have much better support for native than tunnels, although from the post you linked that could be broken too on some.

I just tested.

In the ASUS GT-AX6000, it was initially set to Tunnel 6rd. IPv6 works.

I then changed it to Native, and IPv6 stopped working - cannot ping or browse to ipv6.google.com.
I rebooted the ASUS, and IPv6 Native (DHCPv6-PD) works!
- I can see the IPv6 WAN IP
- Can ping to SingTel DNS 2400:d800::1
- Can ping to ipv6.google.com
- Can browse to ipv6.google.com
- https://test-ipv6.com/ tests show 10/10.

I seriously give up on the TP-Link HB810's IPv6. Either IPv6 does not work, or i do not know the exact settings for it.

I do not wish to use the ASUS as my main router, as it only has 2.5Gbps WAN and LAN ports. My plan is on 5Gbps. It would be under-utilizing what i paid for.

You can consider upgrade to Asus RT-BE88U and keep GT-AX6000 as an AImesh node.

Local version is on the expensive side but China version (from Taobao) is quite okay at RMB 2049. If you sell the TP-Link EB810v at about S$300, the top-up is not much.

You can also consider getting a mini PC with dual SFP+ ports and then use the TP-Link EB810v as an AP. You can choose to run pfSense or OpenWRT. I use an Intel N100 CPU based mini PC with my Singtel 5Gbps plan (bridged ONR) and then use Asus TUF-BE6500 and Asus RT-AX86U as AP.
