Right, we could use one of those ports for the unicast. In fact, that might be a good idea for all IPv6 connections, since the packet could get translated to 6LoWPAN by another node in the network. Would be nice if we could get a kernel API to indicate the desired port range. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
