Aussie Broadband IPv6 and Synology SRM


EDIT 20190725 – A word of warning. I may have identified an issue with the device and its handling of IPv6 services. This may impact the reliability of the Internet connection you use with the device. I will update this article again once I have more certainty about whats going on.

EDIT 20190802 – I think the reliability problems have now been resolved. That’s a long story I may write about another time. In the meantime, ensure your Synology RT2600ac is running SRM 1.2.3 (announcement, download) before you follow the steps below.

I want to share with people how I went about configuring my Synology RT2600ac to work with IPv6 on Aussie Broadband.

This article is not about why you SHOULD enable IPv6. There are many other sites out there that make the case for why you should enable IPv6.

Aussie Broadband offer native IPv6 to their subscribers as a beta product. They don’t have any official information about the service available. Instead it is up to the community over at Whirlpool to try it out, support it, report any problems and help others get it going.

My Synology RT2600ac wireless router has built in native support for IPv6, as all good devices should in this day and age.

The steps to get the AussieBB IPv6 service running with my device were as follows.

First, configure your AussieBB service for IPv6.

  1. Activate IPv6 on your AussieBB profile using the page here. That may take a few minutes to find its way through to your service. Be patient. Its a layer-3 thing so you shouldn’t need to reset your NBN device.
  2. Make a note of the Client IPv6 Prefix (IA-PD) address range the page will display. You will need to know this later when configuring the Synology.

Next, configure your Synology router.

  1. Log in to your Synology’s admin interface. The address to use is the same as you used to set it up.
  2. Open the Network Center app. Screen Shot 2019-07-04 at 1.52.12 pm

  4. In the IPv6 setup: field, select the DHCPv6-PD option.Screen Shot 2019-07-04 at 1.55.15 pm.png
  5. Press Okay to apply the settings and close the window.

Now it’s time to configure the internal network IPv6 configuration.

  1. In the Network Center, click on Local Network.Screen Shot 2019-07-04 at 2.00.26 pm.png
  2. Select IPv6 at the top.Screen Shot 2019-07-04 at 2.05.29 pm

  4. Now you need to select which Prefix to use on your internal network. Click the dropdown to select the prefix from the two available. Ensure you select the network range you noted above labelled Client IPv6 Prefix (IA-PD).Screen Shot 2019-07-04 at 2.09.19 pm.png
  5. Ensure Stateless mode is selected.Screen Shot 2019-07-04 at 2.09.47 pm.png
  6. Press Apply and you’re done.

IPv6 capable devices on your home network (wired or wireless) will start assigning themselves IPv6 addresses.
