How do I forward IPv6 prefix into thread network to reach CoAP server?

Caspar Friedrich

Hi, I currently try to build a little thread network with a border router bridging to ethernet. I did everything like in the Border Router Quick Start Guide and as far as I can say, everything works fine. My problem is now that I need to reach the CoAP server from outside via IPv6. Is there a 'simple' way to modify your example to forward IPv6 prefixes?

Regards Caspar

    Hello, I finally can confirm that the problem was our internal router who provided a /64 address prefix to the border router.

    The solution: I set up a default openWRT router with full IPv6 support and it worked out of the box. The thread border router asked for and got a /62 prefix. Now I can connect to the wifi network of the access point and ping thread devices. CoAP tests are scheduled ;-).

    Everything else is the untouched CoAP client/server example from Nordic.
