I have the strange IPv6 forwarding messages in my security output.

The link-local ip-nr is not lokal on this system, so is there another system 
in my network that does this ipv6.
But I've not yet found a system with fc:ba as last bytes in my arp-table?

Can anybody tell me why I get these messages in my log?
