Stateless autoconfiguration (as you're using with the router advertisements) is intended to work with /64's only. If you can't get more than a /64 from your current provider (and it's quite possible that they're doing a free.fr-style setup so you can *only* have a /64 for the whole connection) then you'll either need a provider offering a larger address space (he.net and sixxs can do this via tunnels) or some other way to assign addresses to hosts so you can subnet instead (simplest being static addressing). I'd go for the tunnel, at least while learning. It's much simpler than subnetting and trying to use protocols designed around /64 with some other mask length. > Running "netstat -rn -f inet6" on the openbsd client host produces: > Internet6: > Destination Gateway Flags > Refs Use Mtu Prio Iface > ::/104 ::1 UGRS > 0 0 - 8 lo0 > ::/96 ::1 UGRS > 0 0 - 8 lo0 > default fe80::20d:b9ff:fe1b:b64d%em0 UG > 0 0 - 4 em0 > > Which seems odd it is showing the link local address of the router/fw > instead of the address I would have expected, the IPv6 address of the router > 2001:55c:62d9:41ed:10::1. Das ist normal.
