Do you have the Dummy Network Interface support in the kernel?

hipd fails to work without that. The dummy network interface is the "plaintext" interface hipd uses to capture the plain packets that need to be encapsulated and sent out, and where it pushes the received packets after they have been decapsulated.

You are right. That was the issue. Thanks.
