Thanks for answering; I got a bit further meanwhile. The first reason my initial tests (following your advice literally) didn't work was that my router does _not_ assign fe80::1 to itself, but rather some other arbitrary address in the fe80 prefix; on close inspection it looks based on the MAC address just like a host is supposed to do. When I ping6 or traceroute6 that specific address, it works. Secondly, while the router seems to obtain a delegated prefix from upstream, it doesn't assign any address from that range to the internal interface. The only ipv6 addresses on the internal interface are the link-local address and the ULA address. Is that normal? I did enable the router advertisement feature, and I checked that the daemon is running on the router. But I can see no output related to that when I run tcpdump on the desktop system. > Here is some data from the Gentoo machine I am currently working on.
