BR fails to route pings K66F + MCR20 #78

Closed bentcooke closed 6 years ago

bentcooke commented 6 years ago

The nanostack BR does not seem to be routing correctly with a static route config. My HW setup is as follows:

1) PC connected to K66F directly via ETH 2) K66F+MCR20 shield 3) KW24D running mesh minimal

The KW24D is connecting to the BR and pulls an IP address, but any attempts to ping this ip address (ping -6) from the PC fails. However, I am able to ping the BR's backhaul address successfully.

The only things changed in mbed_app.json are: radio type -> MCR20 backhaul-dynamic-bootstrap -> false

Building target = K66F

I got the same result when using company PC for pinging RF interface address. However, when I used test PC (no firewall) a ping to RF interface worked fine. I tested with both 6loWPAN ND and Thread configurations.

@bentcooke , would you please try with another PC?

Good point Arto. ARM firewall block IPv6 traffic that is know issue. When you are not arm intranet firewall not accept IPv6.

My old laptop was fixed to support that but I have to request that from IT and it was long journey.

@artokin and @juhhei01, thanks for the feedback and it does appear that the firewall policy was to blame.

The BR is functioning correctly with another PC that is not controlled by IT.
