I test a STM32 nucleo WB55 thread board and are not able to reach external IPV6 server from inside of the created thread network. All my devices appear in the “Thread Topologies” of teh GL-S200 and I’m able to send message inside the network but when I try an exernel IPV6 the border router don’t route de message. I don’t see any error log file except some times “Failed to discover infraif NAT64 prefix: Drop”, is it linked ? How can I debug my problem and see more log on your router ? I tested my external Coap ipv6 server with other coap client and it is reacheable on the internet.
Ok and Is it possible to access global IPV4 from inside the thread network ? It’s related to NAT64 ? Is it working on your border router, because I have such message “Failed to discover infraif NAT64 prefix: Drop”. Where can I found the NAT64 prefix to use ?
For the newbie as me, to get the NAT64 prefix connect to GL-S200 and input this command to see all routes: “ot-ctl netdata show” . The route ending with /96 is the NAT64 prefix. When concatenated with an IPV4 you can reach global IPV4 servers. @gl-inet it should be interesting to display this NAT64 prefix in the WEB admin page ;-).
