Hello,
I'm having a very strange problem with SLIP (tunslip6 from Contiki) on
OpenWRT (fon-ng) and hoping someone can help with investigation.
In short - wpan0 interface with address aaaa::1/64 is created.
ping6 to aaaa::1 is OK
ping6 to aaaa::250:c2a8:c3d4:a645 FAILS. But tcpdump shows ICMP6
requests and replies.
curl to border router web page also times out.
Any hint where the problem could be? Command lines and selected logs are below.
Kind regards,
Maxim
tunslip6 command line:
usr/bin/tunslip6 -B 9600 -s /dev/ttyUSB1 -t wpan0 aaaa::1/64
