IPv6 is finally supported in the latest Malaysian firmware version 3.14.3 Build 150605 Rel.53236n for TP-Link TL-WDR3600 router.
The available IPv6 Internet connection types are:
- DHCPv6
- Static IPv6
- PPPoEv6
- Tunnel 6to4
Here is the way to setup the TP-Link TL-WDR3600 router to support IPv6 network with TM UniFi, using Tunnel 6to4 method.
Go to IPv6 Support > IPv6 Setup, and enable the IPv6, choose "Tunnel 6to4" as the WAN connection type.
Set the MTU Size to be 1472, which is 20 bytes less than the MTU Size of 1492 set for the IPv4 in PPPoE Advanced Settings page.
To make use of Google DNS servers, set your primary and secondary IPv6 DNS servers to be
Leave the LAN IPv6 Address Assign Type as SLAAC.
Click the Save button and you are done. You should be able to see your IPv6 address and settings in the IPv6 Status page now.
You can test your IPv6 connectivity with this website: http://test-ipv6.com/
Note that you won't be able to get a 10/10 score with Tunnel 6to4 connection. The website will just give you a 7/10. This is absolutely fine, as long as you don't get MTU related error which is the common headache in IPv6 setting.
Next, you can compare your Internet access speed to Japan when using IPv4 and IPv6. Both connection speeds are, in fact, surprisingly very different.
