No IPv6 on devices connected to Deco
okay, so my topology is like this:
ISP's Modem -> ISP's Router -> Main Deco -> Switch 1 -> Deco 2 -> Switch 2
Deco 2 is connected to the Main Deco via ethernet backhaul, it is positioned upstairs and Switch 2 is connected to it.
Switch 1 is connected to the Main Deco and some devices are connected to it via ethernet too.
The Main Deco is running on router mode and is directly connected to the ISP's router. All my devices are connected to the Decos, none are connected to the ISP's router.
Internet Connection settings on Deco is as it is, mostly default and auto.
The ISP do provides IPv6 connection. I tested it out and its working when i connected my devices directly to the ISP's router. Just that devices that connects to the Decos can't.
Do note that I must need to have my ISP Router on since i'm using their VoIP service. It is a VoIP router.
Would like to know how to solve it. Thank you in advance.
