Making IPv6 device available on the internet

[Trygve Laugstøl]

Hei

I've gotten the ipv6_coap_server example to run on the nRF51-dongle. I got the bt0 interface after connecting to the device and I am able to ping the device.

My LAN has native IPv6 delivered from my ISP. The gateway router (broadband router) is getting its IPv6 with DHCP-PD and is allocated a /60 range, but is using stateless address configuration on the LAN. My desktop is getting a globally routable IPv6 address and can I can connect to and from the desktop from remote machines.

If I run radvd on my desktop I can give the device a global address, but as far as I know it shouldn't be necessary as my LAN already has a router.

I have tried to bridge the two interfaces with brctl but that fails when adding the bt0 interface.

My setup looks like this:

(nrf51)  <-- BT --> (BT dongle) <- USB -> Linux Host <- ethernet -> DSL router

What do I need to do to get the device to be available on the internet too?

What you need is a bridge on the Linux host between the ethernet device and the bt0 device:

brctl addbr br0

Then add the ethernet device (eth0 below) and the bt0 to the new bridge br0:

brctl addif br0 eth0 bt0

For more details see wiki.debian.org/BridgeNetworkConnections

I should have said so in my question, but I have tried this already. When I try to add the bt0interface I always get Invalid argument. I haven't looked at the sources, but I assume that this is because the bt interface is classified as a POINTTOPOINT interface and not a BROADCAST interface as normal Ethernet interfaces are.

If you have gotten this to work I wonder what your kernel version is and the version of your bridge-utils package is.

Hello Christoph S, and everyone. Does this(brctl addbr br0 ,brctl addif br0 eth0 bt0) means that the Nrf51-DK can be routable from other WAN networks ? Thanks
