Nordic openthread border router

[nehal]

Hi Nordic Community,

I follow the below link to create an openthread border router. I successfully send sensor data on things.io.

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v3.1.0%2Fthread_border_router.html

My Setup is  The border router and the phone/PC in the same local network(connect using  WIFI ), and are supported IPv6.

I want to communicate between phone/PC and node device.

is it possible to do that ping from the node FTD  to PC/phone? 

Any Suggestion!

Nehal....

Hi,

If both Thread node and the phone/PC have global IPv6 connectivity (2000::/3 address), this should be possible.

Can you send me the output from ifconfig on the border router, and the ipaddr output from a CLI node in your Thread network? I would recommend that you send it on a private message directly to me if you have global addresses, as the addresses may be misused if posted in public.

Best regards,
Jørgen

Hi,

From the ifconfig output you can see that in the wlan0 interface, the global IPv6 address of the border router only has a prefixlen of 64. The Thread specifications requires a /64 prefix itself in order to create a global IPv6 subnet for the Thread nodes. In order for the border router to achieve this, it needs a /62 or lower prefix address in order to further subnet the network to the Thread nodes. This is a typical problem with networking equipment/routers that they only provide /64 prefix addresses.

You can still reach IPv4 internet from the Thread nodes and ping PCs/phones via their IPv4 translated addresses through NAT64, but it is harder to ping from the PCs/phone to the Thread nodes. See this post about pinging local IPv4 devices.
