Still working in 2021. Thanks TS for the guide. Please post more tutorial like this, I just got my ER-X hands on after years haha.

I got a doubt that's need to clear. After adding the DNS to the nameserver, I still see TM IPv6 DNS on my device. Is it normal?

Edit: I already reboot my router, AP and phone.

So previously I was able to use IPV6 DNS on LAN device but not the WI-FI devices. Turns out it needs to use the router advertisement for the devices to know the edgerouter is distributing IPV6 DNS instead of TM. (Not sure I explained it in the correct way or not. Sifus please correct me if I'm wrong)

Here's the code I used to enable the router advertisements.





Apply the MSS Clamping on both IPv4 & IPv6





Hope this helps.

I have a ER-X. This is what I do. (Just to give you an idea, not sure if it works for your case.

I assume your router is in fresh factory state
1. Upgrade the firmware to the latest.
2. Go through basic wizard. Insert your all your data required. Do not check any IPv6 related such as delegation / firewall setting.
3. Follow the TS's instruction. Make sure you change according to your own usage. (Interface etc.)
4. Insert the commands in my previous post in terminal. (Change according to your usage as well. For the switch0 part, change to your LAN interface)
5. Done.
