Nordic openthread border router

Question

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, 
 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.
